--- Comment #1 from Mikolaj Zalewski mikolaj.zalewski@gmail.com 2007-10-12 19:51:39 --- It's enough to make any repaint of the dialog to have the preview to show - e.g. if the window manager provides a tooltip for the close button then when the tooltip will disappear, the preview will show.
Dialog has a static control for the preview content. However it doesn't use the control's WM_PAINT to paint the content, but the dialog WM_PAINT uses GetDC on the static control and draws there. If one selects a complicated map one can see that the map is drawn but later is is erased by a dialog WM_ERASEBKGND. Maybe we are missing some message or send them is a wrong order.
