wx.HelpEvent — wxPython Phoenix 4.2.4a1 documentation

A help event is sent when the user has requested context-sensitive help.

This can either be caused by the application requesting context-sensitive help mode via wx.ContextHelp, or (on MS Windows) by the system generating a WM_HELP message when the user pressed F1 or clicked on the query button in a dialog caption.

A help event is sent to the window that the user clicked on, and is propagated up the window hierarchy until the event is processed or there are no more event handlers.

The application should call wx.Event.GetId to check the identity of the clicked-on window, and then either show some suitable help or call wx.Event.Skip if the identifier is unrecognised.

Calling Skip is important because it allows wxWidgets to generate further events for ancestors of the clicked-on window. Otherwise it would be impossible to show help for container windows, since processing would stop after the first window found.

Handlers bound for the following event types will receive a wx.HelpEvent parameter.

• EVT_HELP: Process a wxEVT_HELP event.

• EVT_HELP_RANGE: Process a wxEVT_HELP event for a range of ids.

Inheritance diagram for class

:

__init__

Constructor.

GetOrigin

Returns the origin of the help event which is one of the wx.HelpEvent.Origin values.

GetPosition

Returns the left-click position of the mouse, in screen coordinates.

SetOrigin

Set the help event origin, only used internally by wxWidgets normally.

SetPosition

Sets the left-click position of the mouse, in screen coordinates.

class wx.HelpEvent(CommandEvent)¶

Possible constructors:

HelpEvent(type=wxEVT_NULL, winid=0, pt=DefaultPosition,
          origin=Origin_Unknown) -> None

A help event is sent when the user has requested context-sensitive help.

Methods¶

__init__(self, type=wxEVT_NULL, winid=0, pt=DefaultPosition, origin=Origin_Unknown)¶

Constructor.

Parameters:

• type (wx.EventType)

• winid (wx.WindowID)

• pt (wx.Point)

• origin (HelpEvent.Origin)

Return type:

None

GetOrigin(self)¶

Returns the origin of the help event which is one of the wx.HelpEvent.Origin values.

The application may handle events generated using the keyboard or mouse differently, e.g. by using wx.GetMousePosition for the mouse events.

Return type:

wx.HelpEvent.Origin

GetPosition(self)¶

Returns the left-click position of the mouse, in screen coordinates.

This allows the application to position the help appropriately.

Return type:

wx.Point

SetOrigin(self, origin)¶

Set the help event origin, only used internally by wxWidgets normally.

Parameters:

origin (HelpEvent.Origin)

Return type:

None

SetPosition(self, pt)¶

Sets the left-click position of the mouse, in screen coordinates.

Parameters:

pt (wx.Point)

Return type:

None

Properties¶

Position¶
