The QContextMenuEvent class contains parameters that describe a context menu event. More...
#include <qevent.h>
Inherits QEvent.
Context menu events are sent to widgets when a user triggers a context menu. What triggers this is platform dependent. For example, on Windows, pressing the menu button or releasing the right mouse button will cause this event to be sent.
When this event occurs it is customary to show a QPopupMenu with a context menu, if this is relevant to the context.
Context menu events contain a special accept flag that indicates whether the receiver accepted the event. If the event handler does not accept the event, then whatever triggered the event will be handled as a regular input event if possible.
See also QPopupMenu and Event Classes.
This enum describes the reason the ContextMenuEvent was sent. The values are:
Constructs a context menu event object with the accept parameter flag set to FALSE.
The reason parameter must be QContextMenuEvent::Mouse or QContextMenuEvent::Keyboard.
The pos parameter specifies the mouse position relative to the receiving widget. globalPos is the mouse position in absolute coordinates. state is the ButtonState at the time of the event.
Constructs a context menu event object with the accept parameter flag set to FALSE.
The reason parameter must be QContextMenuEvent::Mouse or QContextMenuEvent::Keyboard.
The pos parameter specifies the mouse position relative to the receiving widget. state is the ButtonState at the time of the event.
The globalPos() is initialized to QCursor::pos(), which may not be appropriate. Use the other constructor to specify the global position explicitly.
Sets the accept flag of the context event object.
Setting the accept flag indicates that the receiver of this event has processed the event. Processing the event means you did something with it and it will be implicitly consumed.
The accept flag is not set by default.
See also ignore() and consume().
Sets the consume flag of the context event object.
Setting the consume flag indicates that the receiver of this event does not want the event to be propagated further (i.e. not sent to parent classes.)
The consumed flag is not set by default.
See also ignore() and accept().
Returns the global position of the mouse pointer at the time of the event.
Returns the global x-position of the mouse pointer at the time of the event.
See also globalY() and globalPos().
Returns the global y-position of the mouse pointer at the time of the event.
See also globalX() and globalPos().
Clears the accept flag of the context event object.
Clearing the accept flag indicates that the receiver of this event does not need to show a context menu. This will implicitly remove the consumed flag as well.
The accept flag is not set by default.
See also accept() and consume().
Returns TRUE if the receiver has processed the event; otherwise returns FALSE.
See also accept(), ignore(), and consume().
Returns TRUE (which stops propagation of the event) if the receiver has blocked the event; otherwise returns FALSE.
See also accept(), ignore(), and consume().
Returns the position of the mouse pointer relative to the widget that received the event.
See also x(), y(), and globalPos().
Returns the reason for this context event.
Returns the button state (a combination of mouse buttons and keyboard modifiers), i.e. what buttons and keys were being pressed immediately before the event was generated.
The returned value is LeftButton, RightButton, MidButton, ShiftButton, ControlButton and AltButton OR'ed together.
Returns the x-position of the mouse pointer, relative to the widget that received the event.
Returns the y-position of the mouse pointer, relative to the widget that received the event.
