If that doesn't work, please file a bug report. Yes it works, it collapses the splitter, but the problem is, you can not "open" again the splitter usig the mouse. Whe you collapse a splitter using the mouse then the weight is zero. That means, it would be a great help, if setting the weight to zero would collapse the splitter too. Before the user closes the application the weights in my application are saved and restored at the next program start. In the case of a collapsed splitter the weight is saved as zero, but when restoring again the splitter is not collapsed anymore. I filled already a bug long time ago (i guess a few month), so indeed i would be happy if somebody would solve it
