How do I:

Switch 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 Selecting Modes.

Move between open files

To quickly move between currently open files, press Ctrl+Tab.

To move forward in the location history, press Alt+Right (Cmd+Opt+Right on macOS). To move backward, press Alt+Left (Cmd+Opt+Left on macOS). For example, if you use the Locator to jump to a symbol in the same file, you can jump back to your original location in that file by pressing Alt+Left.

Switch to 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

Find a specific setting

To find specific settings in Edit > Preferences, use the filter located at the top left of the Preferences dialog.

View output

The taskbar shows output from several sources, such as a list of errors and warnings encountered during a build, detailed output from the compiler, status of a program when it is executed, debug output, or search results.

"Output on the taskbar"

To view different types of output, use the following shortcuts:

  • Issues - Alt+1 (Cmd+1 on macOS)
  • Search Results - Alt+2 (Cmd+2 on macOS)
  • Application Output - Alt+3 (Cmd+3 on macOS)
  • Compile Output - Alt+4 (Cmd+4 on macOS)

For additional ways to view other types of output, see Viewing Output.

Find keyboard shortcuts

Qt Creator has many useful keyboard shortcuts. You can see the keyboard shortcut for a menu command in the menu or the tooltip for a button.

To customize, import, or export keyboard shortcuts, select Edit > Preferences > Environment > Keyboard.

"Keyboard preferences"

Run Qt Creator from the command line

You can launch Qt Creator from the command line using the name of an existing session or project file by entering the name as the command argument.

For example, running qtcreator somesession, launches Qt Creator and loads the session called somesession.

For more information, see Using Command Line Options.

Show and hide sidebars

You can toggle the left and right sidebar in some Qt Creator modes.

To toggle the left sidebar, click (Hide Left Sidebar/Show Left Sidebar) or press Alt+0 (Cmd+0 on macOS).

To toggle the right sidebar, click (Hide Right Sidebar/Show Right Sidebar) or press Alt+Shift+0 (Cmd+Shift+0 on macOS).

For more information on using the sidebars, see Browsing Project Contents.

Move 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.

To jump to a symbol in the current file, press Ctrl+K to open the Locator, enter a period (.), and start typing the symbol name. Then select the symbol in the list. For more information on using the locator, see Searching with the Locator.

Press Ctrl (Cmd on macOS) and click a symbol to move directly to the definition or the declaration of the symbol. You can also move the cursor on the symbol and press F2. For more information, see Moving to Symbol Definition or Declaration.

Quickly locate files using the keyboard

Use the Locator to browse through projects, files, classes, functions, documentation, and file systems. To quickly access files not directly mentioned in your project, you can create your own locator filters. That way you can locate files in a directory structure you have defined.

"List of locator filters"

To create locator filters, select Edit > Preferences > Environment > Locator > Add.

"Locator preferences"

For more information, see Creating Locator Filters.

Perform calculations

Open the Locator with Ctrl+K and type =, followed by a space. You can now do basic calculations, with options to copy the results to the clipboard by navigating through the entries and pressing Enter.

For more information, see Executing JavaScript.

Jump to a function in QML code

Open the Locator with Ctrl+K and type m, followed by a space. You can now go directly to any QML method in the file.

Add a license header template for C++ code

Specify a file that has a license header for C++ in Edit > Preferences > C++ > File Naming > License template.

"File Naming preferences"

The license file may have special placeholders enclosed in %% that are replaced when generating a new file:

  1. %YEAR%: Year
  2. %MONTH%: Month
  3. %DAY%: Day of the month
  4. %DATE%: Date
  5. %USER%: Username
  6. %FILENAME%: File name
  7. %CLASS%: Class name (if applicable)
  8. %$VARIABLE%: Contents of environment variable VARIABLE.

Paste text from my clipboard history

Qt Creator stores copied text in clipboard history. To retrieve clips from the history, press Ctrl+Shift+V until the clip appears. The number of clips in the history is fixed to 10.

Sort lines alphabetically

To sort selected lines alphabetically, select Edit > Advanced > Sort Selected Lines or press Alt+Shift+S (or Ctrl+Shift+S on macOS).

Enclose selected code in curly braces, parentheses, or double quotes

When you have selected code and enter one of the following opening characters, the matching closing character is added automatically at the end of the selection:

  • {
  • (
  • "

To specify whether to automatically insert matching characters, select Edit > Preferences > Text Editor > Completion.

"Completion preferences"

Select the enclosing block in C++

Press Ctrl+U.

Add my own code snippets to the auto-complete menu

You can add, modify, and remove snippets in the snippet editor. To open the editor, select Edit > Preferences > Text Editor > Snippets.

"Snippets preferences"

For more information, see Adding and Editing Snippets.

Quickly write down notes somewhere

Select File > New File > General > Scratch Buffer. Alternatively, Ctrl+N can be used to open this dialog, which is fully navigable via keyboard by using the up and down arrow keys and the tab key.

This creates a new empty text file and saves it to the temporary directory on your machine. You can use it to write down notes without having to worry about deleting the file afterwards. The operating system will eventually remove the file automatically. If you want to keep the file, you can easily save it as a new file somewhere else. If you accidentally close the file, you can find it in the File > Recent Files menu.

Configure the amount of recent files shown

Set the value of Edit > Preferences > Environment > System > Maximum number of entries in "Recent Files".

"System preferences"

Search and replace across files using a regular expression

As an example, say you want to replace equality checks (foo == bar) with a function (foo.equals(bar)):

  1. Ensure that any work you have done is committed to version control, as the changes cannot be undone.
  2. Press Ctrl+Shift+F to bring up the Advanced Find form.
  3. Change the scope to whatever is appropriate for your search.
  4. Under the Search for text field, select the Use regular expressions check box.
  5. Enter the following text in the Search for text field:
    if \((.*) == (.*)\)
  6. Press Search & Replace to see a list of search results.
  7. In the Replace with text field, enter the following text:
    if (\1.strictlyEquals(\2))
  8. Press Replace to replace all instances of the text.

For more information, see Advanced Search.
