Detailed Description

A collection of functions for the conversion of key presses and their modifiers from the window system specific format to the generic format and vice-versa.

Function Documentation

KWINDOWSYSTEM_EXPORT uint KKeyServer::accelModMaskX ( )

Returns bitwise OR'ed mask containing Shift, Ctrl, Alt, and Win (if available).

See also: modXShift(); modXLock(); modXCtrl(); modXAlt(); modXNumLock(); modXWin(); modXScrollLock()

Definition at line 905 of file platforms/xcb/kkeyserver.cpp.

KWINDOWSYSTEM_EXPORT bool KKeyServer::initializeMods ( )

Initialises the values to return for the mod*() functions below.

Called automatically by those functions if not already initialized.

Definition at line 476 of file platforms/xcb/kkeyserver.cpp.

KWINDOWSYSTEM_EXPORT bool KKeyServer::isShiftAsModifierAllowed ( int keyQt )

Test if the shift modifier should be recorded for a given key.

For example, if shift+5 produces '' Qt wants ctrl+shift+5 recorded as ctrl+% and in that case this function would return false.

Since: 4.7.1
