View Full Version : [UNKNOWN][3.1] ItemSelector has no vertical scroll bar when using in a Window

23 Dec 2009, 1:52 PM
In the Example multiselect-demo, the ItemSelector has a vertical scroll bar, if not all items are visible within the height.

When the form containing the ItemSelector is a part of a Window, the vertical scroll bar does not appear even if it is necessary in all browsers. See the screen shots and the example code.

Place this code into a html file and place it into the folder "examples\multiselect". Open the file and show the Window.

I tried you example with Ext 3.1 on various browsers, but all showed a scrollbar.

However, the size of the scrollable area in IE standards mode is wrong (and different for IE6, 7 and 8!).

Strange! If I place my example into ext3.0 Examples, the scroll bars are there. If into ext3.1, no scroll bars.

Maybe, it is due to my new Windows 7 and its theme. I will investigate.

I compared the result code of the examples in the firebug. I found the source of the problem. In the 3.0.0 the code is like

<div id="ext-gen27" class="x-fieldset-body" style="overflow: auto; width: 248px; height: 165px;">

In the 3.1.0

<div id="ext-gen27" class="x-fieldset-body ux-mselect" style="width: 248px; height: 165px;">

And the CSS MultiSelect.css is not included.

However, the size of the scrollable area in IE standards mode is wrong (and different for IE6, 7 and 8!). Yes, I faced that problem also, it makes my life harder, but it is tolerable. Of cause, it would be great if it will be fixed.
