- No, No, No.
- Do it like this. I've done it many time sand it's a doddle.
-
- One vertical XmRowColumn.
- All it's children are XmForms.
- The XmForms hold an XmLabel and an XmText (and whatever else you want).
- Once everything is managed, you can determine the widest XmLabel and widest
- XmText and widest (whatever). Add them all up and set the XmNfractionBase of
- every XmForm (which is a child of teh XmRowColumn) to this value. Then just
- set all the attachments of the XmForm children to XmATTACH_POSITION and the
- XmN(left/right)Position to the appropriate value determined from the
- widest values of each appropriate resource. ie:-
- For all children of each XmForm set the top and bottom attachments to
- XmATTACH_FORM.
-
- For the Label:
-
- XmNleftPosition = 0;
- XmNrightPosition = widest XmLabel width;
-
- For the Text
-
- XmNleftPosition = widest XmLabel width;
- XmNrightPosition = widest XmLabel width + widest XmText width;
-
- For the whatever
-
- XmNleftPosition = widest XmLabel width + widest XmText width;
- XmNrightPosition = you get the picture....
-
- BUT OSF, IT WOULD BE NICE TO HAVE A ROWCOLUMN WHICH DOES DO GENUINE ROWS AND
- COLUMNS WITHOUT ME HAVING TO FART ABOUT LIKE ABOVE.
-
- No I haven't used the Xbae matrix widget. Maybe I should.
