I've started looking at this issue. I hacked the example so it would work
against the source code when put in the demo/examples folder.
I'm looking at the "image" column problem first, under FF.
I added code to QxImagePreloader to change the getWidth and getHeight functions
to include a debug log of the width and height, along with the image name.
On initial loading I saw a load of this in the debug log:
019058: ../../images/blank.gif: width = 1
019068: ../../images/blank.gif: height = 1
On pressing the Populate button there are no further entries, even though the
images are loaded at that point.
The HTML created for the image specified as:
images: { source: "icons/16/thumbnail.png" },
was:
<img width="1" height="1" style="border: 0pt none ; vertical-align: top;"
src="../../themes/icons/crystalsvg/16/thumbnail.png"/>
I put in the full path to a picture, just in case the image manager was causing
a problem:
images: { source:
"d:/abling/packages/ajax/qooxdoo/qooxdoo-play/source/themes/icons/crystalsvg/16/thumbnail.png"
},
This gave the HTML:
<img width="1" height="1" style="border: 0pt none ; vertical-align: top;"
src="d:/abling/packages/ajax/qooxdoo/qooxdoo-play/source/themes/icons/crystalsvg/16/thumbnail.png"/>
The image preloader is not being called again, so something else is being used
to get the image sizes.
Any ideas, Sebastian?
I'll take another look tomorrow.
