Struct qt_gui::QStyleHints

#[repr(C)]pub struct QStyleHints { /* fields omitted */ }

The QStyleHints class contains platform specific hints and settings.

C++ class: QStyleHints.

C++ documentation:

The QStyleHints class contains platform specific hints and settings.

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

Access is read only; typically the platform itself provides the user a way to tune these parameters.

Access to these parameters are useful when implementing custom user interface components, in that they allow the components to exhibit the same behaviour and feel as other components.

Methods

impl QStyleHints

pub fn cursor_flash_time_changed(&self) -> Signal<(c_int,)>

This property holds the text cursor's flash (blink) time in milliseconds.

Returns a built-in Qt signal QStyleHints::cursorFlashTimeChanged that can be passed to qt_core::Signal::connect.

C++ documentation:

This property holds the text cursor's flash (blink) time in milliseconds.

The flash time is the time used to display, invert and restore the caret display. Usually the text cursor is displayed for half the cursor flash time, then hidden for the same amount of time.

C++ documentation:

This property holds 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:

if ((startPos - currentPos).manhattanLength() >=
          QApplication::startDragDistance())
      startTheDrag();
