I have a Label with rich=true holding a load of HTML in a smaller Scroll
but I am not getting scroll bars.
The _getContentHeightForWidth dutifully reports a height of 879 but
strangely getHeight on the label returns null -- perhaps it has yet to
be computed cuz I am printing all this just after assembling the
scroller and label and inserting them in a tab page. Inspecting the
element in firebug I see a height of 65 from the embedded DIV up through
the Scroll, qx inserted contents included.
The tab page in question has a Grow layout, and I could see in Firebug
that as I resized the firbug pane the sizes change to reflect the sapce
available above. (Cool!)
[Note: I just got scrollbars to appear by specifying (not shown below) a
minheight along with the allowGrowY. This was just a desperation hack to
learn what I could learn. It would seem i need a better way than
allowGrowY to fight off the Grow layout on the page, but Scroll is
documented as having a layout that cannot be altered.]
Code looks like this:
processConceptResults: function (e) {
var ctab = this.conceptTab;
ctab.setEnabled(true);
var lbl = new qx.ui.basic.Label().set({
rich: true,
allowGrowY: false,
content: e.getContent()
});
var scroller = new qx.ui.container.Scroll().set({height:200});
scroller.add(lbl);
ctab.add(scroller);
this.tabView.setSelected(ctab);
lbl.debug("lbl content height"+lbl._getContentHeightForWidth());
lbl.debug("lbl height "+lbl.getHeight());
scroller.debug("scroller height "+scroller.getHeight());
},
I will try setting the minHeight programmatically to the height for
width, but that seems wrong. Is there a better way?
cheers, ken
