I'm unsuccessfully trying to use a QgsMapCanvas in a python plugin's dialog.
The canvas renders the map, which appears and disappears the first time I load the dialog. The second time I load the dialog, the map is rendered and remains. However, I've only accomplished this by using waitWhileRendering(), which I know is incorrect. I have posted a minimal plugin on GitHub ( https://github.com/ebrelsford/qgis-map-canvas-test/) demonstrating this issue. It was created using Plugin Builder. The relevant parts will be the .ui file: https://github.com/ebrelsford/qgis-map-canvas-test/blob/master/map_canvas_test_dialog_base.ui#L15 and the dialog python file: https://github.com/ebrelsford/qgis-map-canvas-test/blob/master/map_canvas_test_dialog.py#L55 Is anyone familiar with what I'm doing wrong here? Or does anyone know python plugins using QgsMapCanvas in the dialog that I could use as a reference? I'd appreciate any thoughts you have on it! eric
