/* To: LessTif From: Edouard Parmelan Subject: XmForm and XmATTACH_OPPOSITE_WIDGET Date: Mon, 15 Mar 1999 12:57:59 +0100 Rick, I have found a bug with XmForm and XmATTACH_OPPOSITE_WIDGET. In my application, I have three Widgets label1, label2 and label3 in a form. [In the real life, label1 and label2 are XmRowColumn.] The attachment of label2 are XmATTACH_OPPOSITE_WIDGET for top and bottom to label1, I want the same height for the two labels. label3 have top attachment to label2. In my application, lable2 have a smallest height than label1 and the height of the form is wrong, label3 is layout outside the form :( The result with Motif is correct. If I change the top attachment of label3 to label1, it's correct with Lesstif (and Motif too). I write a small test case what show this bug. Run without argument, the label3 is outside the form (and don't show). You can run it with the parameter ``workaround'' to see the correct form. Hope this help, egp -- Edouard G.
