GTK toggle button to pixmap

verigoth · 07-21-2002, 07:12 PM

i'm finishing up my latest project at sourceforge (http://sourceforge.net/projects/gtz [yahtzee clone]), and this last "bug" is impossible. everytime i change the pixmap (dice image) on the toggle button it tells me "Invalid cast from ToggleButton to Pixmap". normaly, the code should be similar to:

Code:

gtk_pixmap_set(GTK_PIXMAP(GTK_TOGGLE_BUTTON(button)->pixmap), ...);

but i'm using an array of structs that contain the button...so following the above example, it should look like this:

Code:

gtk_pixmap_set(GTK_PIXMAP(GTK_TOGGLE_BUTTON(dice[di-1].button)->pixmap), ...);

in that case i get the compilation error of "Invalid member: pixmap"...
this isn't an emergency situation or anything...but it would be great to get rid of it.

i went 'header diving' last night and found the answer (not suprisingly)...i'm just a little upset that it was not in the tutorial or any documentation. the code above is wrong. what works for ALL cases is this:

Code:

gtk_pixmap_set(GTK_PIXMAP(GTK_BIN(button)->child), ...);
or for the label of a button:
gtk_label_set_text(GTK_LABEL(GTK_BIN(button)->child), "new text");

hope this helps someone else...
