Does anyone have some insight... I am making a widget, subclassed from simple. It is displaying multi lined text (in multiple fonts and colors). I am currently testing it inside of a viewport (Athena) widget, that is inside of a Box (Athena) widget. I.E. Box | Viewport | myWidget When text is added to the widget, instead of drawing the new text in the public procedure, I call the expose method directly (out of laziness, I intend to change it after it is working). Should I not directly call this function? Inside the expose method (Redisplay), if the text overflows the size of the widget (i.e. it not tall enough), then XtMakeGeometryRequest is called requesting that only the height be increased. The problem occurring here is that XtMakeGeometryRequest returns XtGeometryAlmost with a suggestion that the width be 15 pixels more narrow. If I subsequently call XtMakeGeometryRequest with it's own suggestion it returns XtGeometryAlmost again with yet another 15 pixels removed. I tried using XtSetValues to set the height to be taller, and the same problem ocurred. When the widget tried to make itself taller, it collapsed into 0 width. Does anyone know what I'm doing wrong, or has anyone experienced something similar? Also, any program design hints will be humbly accepted. -thanks in advance- ____ ____ ____ Bill Shirley / ___| / ___| / ___| bill@gothamcity.jsc.nasa.gov |_| |_|ciences |_| _______________________________ _omputer _ _ Opinions expressed are obtained| | |___ ___| | | |___orporation by a room full of immortal apes| \____| |____/ \____| with unbreakable typewriters. | ~~~~~~~~~~~DISCLAIMER~~~~~~~~~~~
