Hi,
I finally got something from the code you posted. I made a LCDLabel
widget, which is a simplified version of the LCD gui. There is only 1
row. I also corrected a bug: in the original code, moving the window
made the text disappear.
But I still have some problems:
1) I can't set the text before the label is shown, because the pixmap
does not exist yet... This is a design problem with the current GTK
internals usage :o/
2) The widget does not work when I embed it in my GUI. As I work with
glade, I simply added an empty HBox, and in my code, I instanciate the
LCDLabel, and add it to the HBox.
BTW, is there a better way to embed a custom widget in glade?
Thanks for your help,
