I would like to implement a context/popup menu for a PropertyGrid and offer property-specific commands, e.g. "Export item". The menu would pop up when clicking on the name-field. I do not intend to change the popup menu that is readily provided for the value-field, e.g. Copy&Paste functionality.
PropertyGrid offers an event wx.propgrid.EVT_PG_RIGHT_CLICK. This lets me extract the PGProperty information (name/value) using
def OnRightClick(event):
selectedName = event.GetProperty().GetName()
selectedValue = event.GetProperty().GetValue()
However, this does not offer any location of the mouse event as wx.MouseEvent would:
self.Bind(wx.EVT_RIGHT_DOWN, self.OnRightDown)
def OnRightDown(event):
self.PopupMenu(self, event.GetPosition())
How can I determine the X/Y-location to open a popup menu on the name-field of a PropertyGrid?
The menu is essentially defined as
class PopMenu(wx.Menu):
def __init__(self, parent):
super(PopMenu, self).__init__()
self.parent = parent
popmenu = wx.MenuItem(self, wx.NewId(), 'item')
self.Append(popmenu)
There doesn't appear to be a direct method of getting this information, so you'll have to improvise.
Try using a combination of wx.GetMousePosition
and then use the windows ScreenToClient
function, if you need the position relative to the window.
