Detailed Description

The QStyleHints class contains platform specific hints and settings. \inmodule QtGui.

Since

5.0

An object of this class, obtained from QGuiApplication, provides access to certain global user interface parameters of the current platform.

Access to most settings is read only. The platform itself usually provides the user with ways to tune these parameters. Authors of custom user interface components should read relevant settings to allow the components to exhibit the same behavior and feel as other components.

startDragDistance

QStyleHints::startDragDistance

read

the distance, in pixels, that the mouse must be moved with a button held down before a drag and drop operation will begin.

If you support drag and drop in your application, and want to start a drag and drop operation after the user has moved the cursor a certain distance with a button held down, you should use this property's value as the minimum distance required.

For example, if the mouse position of the click is stored in startPos and the current position (e.g. in the mouse move event) is currentPos, you can find out if a drag should be started with code like this:
