Getting Started with Qt Designer
|
 | Qt Designer's Main Window The menu bar provides all the standard actions for managing forms, using the clipboard, and accessing application-specific help. The current editing mode, the tool windows, and the forms in use can also be accessed via the menu bar. The tool bar displays common actions that are used when editing a form. These are also available via the main menu. The widget box provides common widgets and layouts that are used to design components. These are grouped into categories that reflect their uses or features. |
Since Qt 4.4, you can customize your tool bar by clicking on Tools and selecting Configure Toolbars... to bring up the Customize Toolbars dialog shown below.
Use the Add Button 
to add a custom tool bar and the Remove Button 
to remove a custom tool bar.
Most features of Qt Designer are accessible via the menu bar, the tool bar, or the widget box. Some features are also available through context menus that can be opened over the form windows. On most platforms, the right mouse button is used to open context menus.
 | Qt Designer's Widget Box The widget box provides a selection of standard Qt widgets, layouts, and other objects that can be used to create user interfaces on forms. Each of the categories in the widget box contain widgets with similar uses or related features. Note: Since Qt 4.4, there are some new widgets included, such as: QPlainTextEdit, QCommandLinkButton, QScrollArea, QMdiArea and QWebView. You can display all of the available objects in a category by clicking on the handle next to the category label. When in Widget Editing Mode, you can add objects to a form by dragging the appropriate items from the widget box onto the form, and dropping them in the required locations. Qt Designer provides a scratch pad feature that allows you to collect the most commonly used objects in a separate category. This category will be saved for later use when exiting Qt Designer. The scratch pad category can be filled with any widget currently displayed in a form by simply dragging them from the form and dropping them onto the widget box. These widgets can be used in the same way as any other widgets, but in additon they can contain child widgets. Open a context menu over a widget to change its name or remove it from the scratch pad. |
