|
---|
59 |
|
---|
60 |
|
---|
61 | The QContextMenuEvent class contains parameters that describe a context menu event.
|
---|
62 | <p>
|
---|
63 | <p> Context menu events are sent to widgets when a user triggers a
|
---|
64 | context menu. What triggers this is platform dependent. For
|
---|
65 | example, on Windows, pressing the menu button or releasing the
|
---|
66 | right mouse button will cause this event to be sent.
|
---|
67 | <p> When this event occurs it is customary to show a <a href="qpopupmenu.html">QPopupMenu</a> with a
|
---|
68 | context menu, if this is relevant to the context.
|
---|
69 | <p> Context menu events contain a special accept flag that indicates
|
---|
70 | whether the receiver accepted the event. If the event handler does
|
---|
71 | not accept the event, then whatever triggered the event will be
|
---|
72 | handled as a regular input event if possible.
|
---|
73 | <p> <p>See also <a href="qpopupmenu.html">QPopupMenu</a> and <a href="events.html">Event Classes</a>.

|
---|
76 | <h3 class=fn><a name="Reason-enum"></a>QContextMenuEvent::Reason</h3>
|
---|
77 |
|
---|
78 | <p> This enum describes the reason the ContextMenuEvent was sent. The
|
---|
79 | values are:
|
---|
80 | <ul>
|
---|
81 | <li><tt>QContextMenuEvent::Mouse</tt> - The mouse caused the event to be sent. Normally this
|
---|
82 | means the right mouse button was clicked, but this is platform
|
---|
83 | specific.
|
---|
84 | <li><tt>QContextMenuEvent::Keyboard</tt> - The keyboard caused this event to be sent. On
|
---|
85 | Windows this means the menu button was pressed.
|
---|
86 | <li><tt>QContextMenuEvent::Other</tt> - The event was sent by some other means (i.e. not by
|
---|
87 | the mouse or keyboard).
|
---|
88 | </ul>

|

92 |
|
---|
93 | <p> Constructs a context menu event object with the accept parameter
|
---|
94 | flag set to FALSE.
|
---|
95 | <p> The <em>reason</em> parameter must be <a href="#Reason-enum">QContextMenuEvent::Mouse</a> or <a href="#Reason-enum">QContextMenuEvent::Keyboard</a>.
|
---|
96 | <p> The <em>pos</em> parameter specifies the mouse position relative to the
|
---|
97 | receiving widget. <em>globalPos</em> is the mouse position in absolute
|
---|
98 | coordinates. <em>state</em> is the ButtonState at the time of the event.

101 | </h3>
|
---|
102 |
|
---|
103 | <p> Constructs a context menu event object with the accept parameter
|
---|
104 | flag set to FALSE.
|
---|
105 | <p> The <em>reason</em> parameter must be <a href="#Reason-enum">QContextMenuEvent::Mouse</a> or <a href="#Reason-enum">QContextMenuEvent::Keyboard</a>.
|
---|
106 | <p> The <em>pos</em> parameter specifies the mouse position relative to the
|
---|
107 | receiving widget. <em>state</em> is the ButtonState at the time of the
|
---|
108 | event.
|
---|
109 | <p> The <a href="#globalPos">globalPos</a>() is initialized to <a href="qcursor.html#pos">QCursor::pos</a>(), which may not be
|
---|
110 | appropriate. Use the other constructor to specify the global
|
---|
111 | position explicitly.

|
---|
114 | </h3>
|
---|
115 |
|
---|
116 | <p> Sets the accept flag of the context event object.
|
---|
117 | <p> Setting the accept flag indicates that the receiver of this event
|
---|
118 | has processed the event. Processing the event means you did
|
---|
119 | something with it and it will be implicitly consumed.
|
---|
120 | <p> The accept flag is not set by default.

121 | <p> <p>See also <a href="#ignore">ignore</a>() and <a href="#consume">consume</a>().

|

124 | </h3>
|
---|
125 |
|
---|
126 | <p> Sets the consume flag of the context event object.
|
---|
127 | <p> Setting the consume flag indicates that the receiver of this event
|
---|
128 | does not want the event to be propagated further (i.e. not sent to
|
---|
129 | parent classes.)
|
---|
130 | <p> The consumed flag is not set by default.

156 |
|

157 | <p> Clears the accept flag of the context event object.
|

158 | <p> Clearing the accept flag indicates that the receiver of this event
|

159 | does not need to show a context menu. This will implicitly remove
|

160 | the consumed flag as well.

175 | receiver has blocked the event; otherwise returns FALSE.
