Switching between modes
Qt Creator uses different modes for different purposes. You can quickly switch between these modes with the following keyboard shortcuts:
- Welcome mode Ctrl+1
- Edit mode Ctrl+2
- Design mode Ctrl+3
- Debug mode Ctrl+4
- Projects mode Ctrl+5
- Help mode Ctrl+6
For more information about Qt Creator modes, see Qt Creator Modes.
Moving Between Open Files
To quickly move between currently open files, press Ctrl+Tab.
Moving To the Edit Mode
To move to the Edit mode and currently active file, press Esc.
If you already are in the Edit mode:
- The first press moves focus to the editor
- The second press closes secondary windows
Using the Filter in Options Dialog
To find specific settings you require in Tools > Options... use the filter located at the top left of the Options dialog box.
Using Keyboard Shortcuts
Qt Creator provides many useful keyboard shortcuts.
To customize, import or export keyboard shortcuts, select Tools > Options... > Environment > Keyboard.
Running Qt Creator From Command Line
You can launch Qt Creator from command line using the name of an existing session or .pro file by giving the name as the command argument.
For example, running qtcreator somesession, launches Qt Creator and loads session somesession.
Note: Make sure Qt Creator is included in the PATH environment variable. This can be done by typing the following in the command line:
Showing and Hiding the Sidebar
To toggle the sidebar in the Edit and Debug modes, click or press Alt+0 (Cmd+0 on Mac OS X).
For more information on using the sidebar, see Browsing Project Contents.
Moving To Symbols
To move straight to a symbol used in a project, select the symbol in the Editor toolbar drop-down menu.
For more information on the editor toolbar, see Using the Editor Toolbar.
Displaying Signals and Slots
If an instance of a class is derived from QObject, and you would like to find all other objects connected to one of your object's slots using Qt's signals and slots mechanism, select Tools > Options... > Debugger > Debugging Helper > Use Debugging Helper.
In the Locals and Watchers view, expand the object's entry and open the slot in the slots subitem. The objects connected to this slot are shown as children of the slot. This method works with signals too.
Displaying Low Level Data
If special debugging of Qt objects fails due to data corruption within the debugged objects, you can switch off the debugging helpers. When debugging helpers are switched off low-level structures become visible.
To switch off the debugging helpers:
- Select Tools > Options... > Debugger > Debugging Helper.
- Uncheck the Use Debugging Helper checkbox.
