## Reference: Dialogs

### Introduction

This chapter describes and explains every Qt Designer dialog.

### The File Dialogs

> New File Dialog

#### New File Dialog

Click File|New (or press Ctrl+N) to invoke the New File dialog. This dialog offers four kinds of file to choose from: C++ Project, Forms, Source files, and Main files.

The 'Insert Into' drop-down combobox lists the open projects, defaulting to the current project. New files are added to the project displayed in this combobox. To add a new file to a different project, choose the project you want to use in the 'Insert Into' combobox.

The 'Dialog' file type is highlighted by default when the New File dialog pops up. Click on the file type you want to use and click OK to create it. Click Cancel to leave the dialog without creating a new file. Note that if you select C++ Project, the 'Insert Into' combobox will be disabled, since it is not possible to insert a new C++ Project into an existing project.

##### C++ Project Files

Click C++ Project to start a new project. This option invokes the Project Settings Dialog. C++ projects are saved as `.pro` files, which include the information Qt Designer needs to manage projects. When you add a form to your project in Qt Designer, it is automatically added to the FORMS section of the project file. The `.pro` file contains the list of forms (`.ui` files) used in the project. Qt Designer reads and writes `.ui` files, e.g. form.ui. The uic (user interface compiler) creates both a header file, e.g. form.h, and an implementation file, e.g. form.cpp, from the `.ui` file.

##### Dialog Forms

Click Dialog to create a plain dialog form. Typically, this type of form is used to present the user with configuration options, or to present related sets of choices, for example, printer setting dialogs and find and replace dialogs.

##### Wizard Forms

Click Wizard to create a wizard form. A wizard is a special type of input dialog that consists of a sequence of dialog pages. A wizard's purpose is to assist a user by automating a task by walking the user through the process step by step. Wizards are useful for complex or infrequently occurring tasks that people may find difficult to learn or do. Initially the wizard form consists of a single dialog page. Use the right click context menu to add additional pages and to change page titles.

##### Widget Forms

Click Widget to create a form whose superclass is QWidget rather than QDialog.

##### Main Window Form

Click Main Window to invoke the Main Window Wizard. This wizard is used to create actions, menu options and toolbars through which the user can invoke actions. This form is used to create typical main-window style applications.

##### Configuration Dialog Form

Click Configuration Dialog creates a form with a listbox on the left, and a tabwidget filling the body of the form, along with Help, OK and Cancel buttons.

##### Dialog with Buttons (Bottom) Form

The Dialog with Buttons (Bottom) form is a template with default buttons at the bottom of the form.

##### Dialog with Buttons Form (Right)

The Dialog with Buttons (Right) form is a template with default buttons at the right of the form.

##### Tab Dialog Form

The Tab Dialog form has a tab widget as its central widget, along with Help, OK and Cancel buttons along the bottom.

##### C++ Source File

Click C++ Source File to create a new empty C++ file. The file will automatically be added to the project when it is saved.

##### C++ Header File

Click C++ Header File to create a new empty C++ header file. The file will automatically be added to the project when it is saved.

##### C++ Main File

Click C++ Main File to invoke the Configure Main-File Dialog which will create a basic `main.cpp` file automatically.

> File Open Dialog

#### File Open Dialog

Click File|Open (or pressCtrl+O) to invoke the Open dialog. Use this dialog to open existing files.

The Open dialog shows the current directory and default file type. To choose a different directory, click the 'Look In' combobox. Choose a file and the name will appear in the 'File Name' combobox. To choose a different file type, click the 'File Type' combobox. Click the 'Create New Folder' toolbar button to create a new directory. Click the 'List View' toolbar button to view folders and files in a list with only the names showing. Click the 'Details' toolbar button to view the folders and file names along with their size, type, date, and attributes. Click the Size, Type, Date, or Attributes column headers to sort the folders or files.

Click Open to open the selected file. Click Cancel to leave the dialog without opening a new file.

Note: For Windows, the System File Dialogs are used.

> Save As

#### Save As

Click File|Save As to invoke the Save As dialog. Use this dialog to save files to a directory.

The Save As dialog shows the current directory and default file type. To choose a different directory, click the 'Look In' combobox. Choose a file and the name will appear in the 'File Name' combobox. To choose a different file type, click the 'File Type'combobox. Click the 'Create New Folder' toolbar button to create a new directory. Click the 'List View' toolbar button to view folders and files in a list with only the names showing. Click the 'Details' toolbar button to view the folders and file names along with their size, type, date, and attributes. Click the Size, Type, Date, or Attributes column headers to sort the folders or files.

Click Save to save the selected file. Click Cancel to leave the dialog without saving the file.

Note: For Windows, the System File Dialogs are used.

> Create Template

#### Create Template Dialog

Click File|Create Template to invoke the Create Template dialog. Use this dialog to create templates.

The 'Template Name' line edit defaults to 'New Template'. To change the name to a different name, type it in the line edit. Click the 'Baseclass for Template' scroll bar to choose a base class for the template.

Click Create to create the template. Click Cancel to leave the dialog without creating a template.

If you create a template it will appear in the New File Dialog. Templates are useful when you have to produce a large number of similar forms, or where you want to 'brand' your forms.

### The Edit Dialogs

> Edit Slots

#### Edit Slots Dialog

Click Edit|Slots to invoke the Edit Slots dialog. Use this dialog to edit or create slots which are used in conjunction with signals to provide communication between objects.

When this dialog is invoked, all existing slots are shown in the 'Slot' listbox. The column headers Slot, Type, Specifier, Access, and In-Use provide details about each slot that is listed. Click on any of the column headers to sort the slots. To create a new slot, click the New Slot button. The new slot has a default name that you should replace by typing the new name in the 'Slot' line edit. The 'Return Type' is also a default that can be changed by typing in the line edit. To change the 'Specifier' or 'Access', click the combobox and choose the required specifier or access. To remove a slot, click the slot you want to delete, and then click the Delete Slot button.

Click OK to save all changes made to slots. Click Cancel to leave the dialog without making any changes to slots.

> View Connections

#### View Connections Dialog

Click Edit|Connections to invoke the View Connections dialog. This dialog displays the current signals and slots connections.

When this dialog is invoked, all existing connections are shown in the listbox. The column headers Sender, Signal, Receiver, and Slot provide details about each connection. Click the column headers to sort the connections. To remove a connection from the listbox, click the connection you want to disconnect and then click Disconnect. To edit a connection, click the Edit... button to invoke the Edit Connections Dialog.

Changes made in this dialog take immediate effect. Click the Close button to leave the dialog.

> Form Settings

#### Form Settings Dialog

Click Edit|Form Settings to invoke the Form Settings dialog. Use this dialog to save the form's settings, pixmap, and layout properties.

##### Settings

In the Settings section, you can change or add the name of the class that will be created by typing in the 'Class Name' line edit. Note that the default name is the form name, but it can be changed. You can also enter text to the 'Comment' and 'Author' line edits or leave them blank, since they are not required.

##### Pixmaps

The default (for projects) is 'Project Imagefile'. This is the recommended option. Images are handled automatically, with Qt Designer storing the images in a subdirectory, and `uic` producing code that contains the images and the necessary supporting code. Each image is stored just once, no matter how many forms it is used in.

If you do not want Qt Designer to handle the images, (or are not using a project) choose either 'Save Inline' or 'Use Function'. 'Save Inline' saves the pixmaps in the `.ui` files. The disadvantage of this approach is that it stores images in the forms in which they're used, meaning that images cannot be shared across forms. Click 'Use Function' to use your own icon-loader function for loading pixmaps. Type the function's name (with no signature) in the 'Use Function' line edit. This function will be used in the generated code for loading pixmaps. Your function will be called with the text you put in the pixmap property (e.g. the image name) whenever an image is required.

##### Layouts

Click the 'Default Margin' spinbox or the 'Default Spacing' spinbox to change the default layout of the current form.

Click OK to accept changes to the form settings. Click Cancel to leave the dialog without making any changes.

#### Preferences Dialog

Click Edit|Preferences to invoke the Preferences dialog. This dialog has a tab for 'General' preferences. If you have the C++ Editor plugin, the dialog will also have a tab for the C++ Editor.

> Preferences- General Tab

##### General Tab

The 'General' tab has sections for Background, Grid, General, and Toolbars.

The Background section defaults to 'Pixmap'. To change the default, click the Select a Pixmap button next to the 'Pixmap' radio button to invoke the Choose a Pixmap... Dialog. Click the 'Color' radio button to change the background to a color instead of a pixmap. Click the Choose a Color button located to the right of the 'Color' radio button to invoke the Select Color Dialog.

The 'General' section of the General tab has three checkboxes that are checked by default. Click the 'Restore last workspace on startup' checkbox to save the size and positions of the windows and toolbars of Qt Designer. The next time you start up Qt Designer, the windows and toolbars are restored to their last positions. Click the 'Show Splash Screen on startup' checkbox to display the Qt Designer splash screen when you start up the application. Click the 'Disable Database Auto-Edit in Preview' checkbox to disable the ability to update or delete data in the database to which you are connected when working with database widgets. To change the path Qt Designer uses to find it's online documentation, click the 'Documentation Path' line edit and type a new path. It would be unlikely to have to change this path. Another way to change the path is to click the (ellipsis) button located to the right of the line edit. This invokes the Find Directory Dialog.

The 'Grid' section has options for customizing the grid on the form. The 'Show Grid' checkbox located above the 'Grid' section is checked by default. Developers using Qt Designer almost always use Qt's layouts to design their forms and rarely make any use of the grid. The grid is provided for the rare occasions when a form is created using widgets with fixed sizes and positions. When 'Show Grid' is checked, you can customize the grid's appearance. When it is unchecked, the 'Grid' section is disabled. The 'Snap to Grid' checkbox is also checked by default. When it is checked, widgets are placed on a dot (snap to the grid) using the X|Y resolution. When it is unchecked, the 'Grid-X' and 'Grid-Y' spin boxes are disabled. Click the 'Grid X' and 'Grid Y' spinboxes to customize the grid settings for all forms.

The 'Toolbars' section has a 'Show Text Labels' checkbox. Click the checkbox to display the text labels for each icon shown in the Qt Designer toolbar.

> Preferences- C++ Editor Tab

##### C++ Editor Tab

The C++ Editor tab provides options for customizing the editor. The 'Syntax Highlighting' section lets you change the way the syntax is viewed in the editor. Click the 'Element' listbox and choose an element. Click the 'Family' listbox to change the font style for that element. Click the 'Size' spinbox to choose a font size. You can change the font to Bold, Italic, or Underline by clicking the corresponding checkbox. Note, that all the fonts used derive from the 'Standard' element, so if you want to change the font used for everything, change the 'Standard' element. Click the Color button to invoke the Select Color Dialog. As you make changes to each element, you can view the changes in the 'Preview' line edit.

The 'Options' section has the Wordwrap, Completion, and Parentheses Matching checkboxes checked by default. Click the checkboxes to de-select them.

Click OK to accept changes to Preferences dialog. Click Cancel to leave the dialog without making any changes.

### The Project Dialogs

> Add Dialog

#### Add Dialog

Click Project|Add File to invoke the Add dialog. Use this dialog to add files to the current project.

To choose a different file type, click the 'File Type' combobox. Click the 'Create New Folder' toolbar button to create a new directory. Click the 'List View' toolbar button to view folders and files in a list with only the names showing. Click the 'Details' toolbar button to view the folders and file names along with their size, type, date, and attributes. Click the Size, Type, Date, or Attributes column headers to sort the folders or files.

Click Open to open the selected file. Click Cancel to leave the dialog without opening a file.

> Manage Image Collection

#### Image Collection Dialog

Click Project|Image Collection to invoke the Manage Image Collection Dialog. Use this dialog to view the project's images, add new images, or delete images.

To add an image, click the Add button to invoke the Choose Images... Dialog. To delete an image from from the iconview, click the image and then click the Delete button.

Changes made to the image collection are applied immediately. Click the Close button to leave the dialog.

> Edit Database Connections

#### Edit Database Connections Dialog

Click Project|Database Connections to invoke the Edit Database Connections Dialog. Use this dialog to connect your project to a database or to edit the current connections.

Click New Connection to create a new database connection. For applications that use a single database it will probably be most convenient to use the default connection name of '(default)'. If you use more than one database then each one must be given a unique name. A driver must be chosen from the Driver combo box. The database name may be available in the Database Name combo box or may have to be typed in. The database name, username, password and hostname should be provided by your database system administrator. When the Connection information has been completed click Connect. If the connection is made the connection name will appear in the list box on the left hand side of the dialog.

To remove a connection, click the connection in the listbox and then click the Delete Connection button.

Click Close to leave the Database Connections dialog.

#### Project Settings Dialog

Click the 'Template' combobox and choose application or library to create makefiles for building applications or libraries. Click the 'Config' combobox to select the project configuration and compiler options for all platforms, or specific platforms. Type the Config value in the line edit. Note: Unix defaults to a shared library. If you want a shared library in Windows, type 'dll' at the end of the default config command and make sure you select lib from the Template combobox. Click the 'Libs' combobox to select a platform. Type the libraries in the line edit. Click the 'Defines' combobox and select a platform. 'Defines' values are added as compiler pre-processor macros. Type the 'Defines' values in the line edit. Click the 'Includepath' combobox to select a platform. Includepath specifies the directories that should be searched for include files when compiling the project. Type the 'Includepath' values in the line edit.

Cick OK to accept changes to the project settings. Click Cancel to exit the dialog without making any changes to the project settings.

### The Search Dialogs

> Find Text

#### Find Text Dialog

Click Search|Find (or press Ctrl+F) to invoke the Find Text Dialog. Use this dialog to find specific text in a project file.

To find the text you want in a file, type the text in the 'Find' combobox. You can make the search more specific by checking any or all of the checkboxes in the 'Options' section. Click the 'Whole words only' checkbox to narrow the search to whole words. Click 'Case Sensitive' to search for text that is identical to the text typed in the combobox. Click 'Start at Beginning' to start the search from the beginning of the file. The 'Direction' section offers the 'Forward' radio button and the 'Backward' radio button to specify the direction to perform the search in the file. Click the Find button to start the search. When the text is found, it is highlighted in the file. Continue clicking Find to search for subsequent occurrences of the search text.

Click the Close button to leave the dialog.

> Replace Text

#### Replace Text Dialog

Click Search|Replace (or press Ctrl+R) to invoke the Replace Text Dialog. Use this dialog to replace text in a project file.

To replace text, type the text you would like to replace in the 'Find' combobox. Type the new text in the 'Replace' combobox. You can make the search more specific by checking any or all of the checkboxes in the 'Options' section. Click the 'Whole words only' checkbox to narrow the search to whole words. Click 'Case Sensitive' to search for text that identical to the text you typed in the combobox. Click 'Start at Beginning' to start the search from the beginning of the file. The 'Direction' section offers the 'Forward' radio button and the 'Backward' radio button to specify the direction to perform the search in the file.

Click the Replace button to search and replace the text. When the text is found, it is highlighted in the file. Continue clicking Replace button to search and replace each occurrence of the text in the file. Click Replace All button to replace all occurences of the search text in the file at once.

Click the Close button to leave the dialog.

> Goto Line

#### Goto Line Dialog

To change the default file name, type it in the 'Filename' line edit. Choose the form to use as the application's main form from the line edit by clicking it.

Click OK to accept the configurations and Qt Designer will create a default `main.cpp` file. Click Cancel to leave the dialog.

Note for database programmers: If you create a `main.cpp` file using Qt Designer, this file will not include the `createConnections()` function. We do not include this function because it needs the username and password for the database connection, and you may prefer to handle these differently from our simple example function. As a result, applications that preview correctly in Qt Designer will not run unless you implement your own database connections function.

> Save Project Settings

### Save Project Settings Dialog

The Save Project Settings message box is invoked by clicking File|Close or File|Exit for an open project with unsaved changes. The dialog displays the text 'Save changes to your project.pro'?.

Click OK to accept the pixmap file. Click Cancel to leave the dialog without choosing a pixmap file.

### Edit Custom Widgets Dialog

Invoke this dialog by clicking Tools|Custom|Edit Custom Widgets. Use this dialog to create custom widgets.

Custom widgets are created in code. They may contain a combination of existing widgets but with additional functionality, slots and signals, or they may be written from scratch, or a mixture of both. A custom widget is often a specialization (subclass) of another widget or a combination of widgets working together or a blend of both these approaches. If you simply want a collection of widgets in a particular configuration it is easiest to create them, select them as a group, and copy and paste them as required within Qt Designer. Custom widgets are generally created when you need to add new functionality to existing widgets or groups of widgets. To add create a new widget, click the New Widget button. You will find more information about adding new widgets in the 'Definitions Section'. To load a file which contains descriptions of custom widgets, click the Load Descriptions button.
