Hi:
I am drawing on a wxScrolledWindow using the following commands which seem to work:
···
----------------------------
x, y = event.GetPositionTuple()
dc = wxClientDC( self )
dc.SetMapMode( wxMM_METRIC )
self.PrepareDC( dc )
pos = dc.DeviceToLogicalX( x ), dc.DeviceToLogicalY( y )
----------------------------
In my update window method I have a customized onPaint as follows:
----------------------------
data = self.doc.getDData()
dc = wxPaintDC( self )
self.PrepareDC( dc )
dc.BeginDrawing()
for object in data:
colour = object.getColour()
lWidth = object.getPWidth()
points = object.getCoords()
pen = wxPen( wxNamedColour( colour ), lWidth, wxSOLID )
dc.SetPen( pen )
for line in points:
x1, y1, x2, y2 = line
pos = ( dc.LogicalToDeviceX( x2 ), dc.LogicalToDeviceY( y2 ),
dc.LogicalToDeviceX( x1 ), dc.LogicalToDeviceY( y1 ) )
apply( dc.DrawLine, pos )
dc.EndDrawing()
----------------------------
This does not work. My drawn items get drawn correctly but on update, they do not appear correctly.
Does anybody know why? Please help
