[jira] Created: (XAP-24) Widgets: Checkbox/RadioButton:
imagePressed/imagePressedSelected should preload given image.
Widgets: Checkbox/RadioButton: imagePressed/imagePressedSelected should preload given image.
--------------------------------------------------------------------------------------------
Key: XAP-24
URL: http://issues.apache.org/jira/browse/XAP-24
Project: XAP
Issue Type: Bug
Reporter: Trevor Oldak
Priority: Trivial
Checkboxes and radiobuttons can display an image instead of the widget when they are clicked, to enhance the look and feel.
However, these images are not loaded until they are needed. Since clicks are usually very fast actions, the image won't have enough time to display. This could be avoided by preloading hte image with the javascript Image() object.
var temp=new Image(0,0);//gives the dimensions of the image
temp.src=url;
That will load the image into cache, so that even if the temp variable isn't used or is assigned a different value, the image will still be in cache.
