Re: Child Packing

hi, there is a logical explanation to this problem in the manual : "Note that all children in a GtkVBox are allocated the same width, regardless of settings and child requisition size. Widgets taking up less than the allocated width are by default centered within the available area in that dimension." To get rid of this you can either use gtktable as said by Nghia, or if you still want to use boxes you must use some gtkhbox inside the vbox to contain your widgets, this way only the hbox will be as width than the vbox but your widgets inside will keep their setted width. $hb = &new gtkhbox(0,0); $button = &new GtkButton('button'); $hb->pack_start($button); $cd_type_main_box->pack_start($button, false, false, 10); the previous sample will be helpfull when you have lines with multiple widgets, but in your case you only have 1 widgets by lines. So a quick way to do what's you need is to simply add your vbox in a hbox and put the hbox in the window, this would solve your problem. $cd_type_main_box = &new GtkVBox(false, 0); $cd_type_main_box->set_usize(100,-1); $hb = &new gtkhbox(0,0); $hb->pack_start($cd_type_main_box,0,0,10); $cd_type_window->add($hb); regards,
