Frequently asked questions ( 5 )

Q

Whether the QT creator is an open source?

A

Yes, the QT creator is an open source application.

Q

Qt Creator only shows a blank window, a dialog complaining about missing OpenGL support, or crashes on startup. What's going wrong?

A

Some parts of Qt Creator use Qt Quick 2, which relies on OpenGL API for drawing. The most prominent use of Qt Quick 2 is in the Welcome mode, but it's also used for the Qt Quick Designer, and the QML Profiler.

Unfortunately the use of OpenGL can cause problems, especially in remote setups and with outdated drivers. You can quickly check whether this is your problem by:

Launching Qt Creator with Welcome mode disabled ( -noload Welcome on command line).
Checking the console or the Windows debugger log for OpenGL-related error messages.

Q

How do I reset all Qt Creator settings?

A

Qt Creator creates the following files and directories:

QtCreator.db
QtCreator.ini
qtversion.xml
toolChains.xml
qtcreator
qtc-qmldump

Q

Qt Creator comes with MinGW, should I use this version with Qt?

A

Use the version that was built against the Qt version.

Q

Qt Creator does not find a helper application, such as Git or a compiler. What should I do?

A

Make sure that the application is in your system PATH when starting Qt Creator. Also select Tools > Options to check the settings specified for the application. Many plugins specify either the path to the tool they need or the environment they run in.

This is especially relevant for the OS X where /usr/local/bin might not be in the path when Qt Creator is started.
