Detailed Description
Context menu events are sent to widgets when a user performs an action associated with opening a context menu. The actions required to open context menus vary between platforms; for example, on Windows, pressing the menu button or clicking the right mouse button will cause this event to be sent.
When this event occurs it is customary to show a QMenu with a context menu, if this is relevant to the context.
Member Type Documentation
enum QContextMenuEvent::Reason
This enum describes the reason why the event was sent.
Constant | Value | Description |
---|---|---|
QContextMenuEvent::Mouse | 0 | The mouse caused the event to be sent. Normally this means the right mouse button was clicked, but this is platform dependent. |
QContextMenuEvent::Keyboard | 1 | The keyboard caused this event to be sent. On Windows, this means the menu button was pressed. |
QContextMenuEvent::Other | 2 | The event was sent by some other means (i.e. not by the mouse or keyboard). |
Member Function Documentation
QContextMenuEvent::QContextMenuEvent(QContextMenuEvent::Reason reason, const QPoint &pos)
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.
The globalPos() is initialized to QCursor::pos(), which may not be appropriate. Use the other constructor to specify the global position explicitly.
QContextMenuEvent::QContextMenuEvent(QContextMenuEvent::Reason reason, const QPoint &pos, const QPoint &globalPos, Qt::KeyboardModifiers modifiers = Qt::NoModifier)
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. The modifiers holds the keyboard modifiers.
const QPoint &QContextMenuEvent::globalPos() const
Returns the global position of the mouse pointer at the time of the event.
int QContextMenuEvent::globalX() const
Returns the global x position of the mouse pointer at the time of the event.
See also globalY() and globalPos().
int QContextMenuEvent::globalY() const
Returns the global y position of the mouse pointer at the time of the event.
See also globalX() and globalPos().
const QPoint &QContextMenuEvent::pos() const
Returns the position of the mouse pointer relative to the widget that received the event.
See also x(), y(), and globalPos().
QContextMenuEvent::Reason QContextMenuEvent::reason() const
Returns the reason for this context event.
int QContextMenuEvent::x() const
Returns the x position of the mouse pointer, relative to the widget that received the event.
int QContextMenuEvent::y() const
Returns the y position of the mouse pointer, relative to the widget that received the event.
