Hello,
I'm developing my custom layout (mentioned previously in this list). I've been
studing the code of qooxdoo layouts for a while, then created my own. It
works OK when children are simple widgets.
But it fails when the child is layout (for example CanvasLayout). I.e. it
doesn't force the child layout update. What should I call in *Impl to force
child update?
The main thing what I'm doing there is _apply* methods? Is there any other
method (to call or implement) which will fix that?
Here is what my *Impl class looks like:
qx.Proto.updateChildOnInnerWidthChange = function(vChild)
{
vChild.addToLayoutChanges("location");
return true;
}
qx.Proto.layoutChild = function(vChild, vJobs) {
var widget = this.getWidget();
var width = widget.getInnerWidth();
if(width != this._prevWidth) {
widget._recomputeColumnWidth();
widget._recomputeColumns();
this._prevWidth = width;
}
var config = widget._config[vChild._placeId];
var columns = widget._columns;
var isLabel = vChild instanceof qx.ui.basic.Label;
if(isLabel) {
var column = columns[config.startCol + '_'];
vChild._applyRuntimeLeft(column.left + column.width -
config._labelWidth);
vChild._applyRuntimeTop(config.top);
}
else {
var startCol = columns[config.startCol];
var endCol = columns[config.endCol];
vChild._applyRuntimeLeft(startCol.left);
vChild._applyRuntimeWidth(endCol.start[config.startCol]);
vChild._applyRuntimeTop(config.top);
vChild._applyRuntimeHeight(config.height);
}
}
Thanks,
Alexei Golovko
