1) I would like to be able to pass parameters into my gtkbasic program, can anyone explain the syntax of how I read them in gtkbasic.
2) The window slides slowly up the screen 1 pixel at a time but as it slides onto the screen only the first 40 or so rows of pixels in the label are displayed. If I pop the window fully onscreen and then move it the display is fine. Once the window has reached its final position I can use gtk_widget_hide followed by gtk_widget_show to force a refresh, but executing this for every 1 pixel move causes flicker (unsurprisingly).
I have fixed this by doing hide then show once every 20 pixels but I wonder if there is a better way.
