Hi again,
...answering parts of my own question here:
I've managed to make a *workaround* for my issue by placing this code
---------------------------------------------------------------------
// Default fallback-width: 16 pixel
treeItem.getChildControl("icon").setWidth(
qx.util.ResourceManager.getInstance().getImageWidth(vIcon) || 16
);
---------------------------------------------------------------------
into the '__createTreeFile' method (see below)
But the question is:
Shouldn't this be done in the qx.ui.tree.TreeFile#setIcon method?
At least it seems to be that it was done "back in the old 1.2.1 days" ;)
For completeness, here's the code including my workaround:
---------------------------------------------------------------------
__createTreeFile : function (iconUrl)
{
var treeItem = new qx.ui.tree.TreeFile();
treeItem.addIcon();
treeItem.setIcon(iconUrl);
// **WA** Default fallback-width: 16 pixel
treeItem.getChildControl("icon").setWidth(
qx.util.ResourceManager.getInstance().getImageWidth(vIcon) || 16
);
// **WA-End**
var checkbox = new qx.ui.form.CheckBox();
checkbox.setFocusable(false);
checkbox.setTriState(true);
treeItem.addWidget(checkbox);
treeItem.addLabel(vLabel);
return treeItem;
}
---------------------------------------------------------------------
I hope (something like) this will be included into qx.ui.tree.TreeFile#setIcon
or qx.ui.tree.TreeFile#addIcon so I can remove this work-around
Thanks and regards,
Peter
