tab body container height is truncated in FF

[daveh0]

I have a very basic TabPanel with 3 tabs. The content of the 1st tab is very long and therefore must be scrolled. The height of the scrolling area is supposed to take up the entire body of the TabPanel. This displays as expected when there is only 1 tab (see screen shot 1), but for each subsequent tab added the height of the scrolling area of Tab 1 is decreased by about 20px (see screen shots 2 and 3).

Here is my code:

    gTabs = new Ext.TabPanel({
          id: 'gTabs'
        , renderTo: 'int'
        , height: 400
        , activeTab: 0
        , items: [{
              title:'Tab 1'
            , contentEl: 'content_tab1'
            , autoScroll:true
        },{
              title: 'Tab 2'
            , html: 'Tab 2 content'
        },{
              title:'Tab 3'
            , html: 'Nothing to see in Tab 3'
        }]
    });

and relevant HTML

    <div id="int" style="width:500px;height:400px;background:#fff;overflow:hidden;"></div>
    <div id="content_tab1" class="x-hide-display">

    </div>

This is only happening in FF. It does not happen if I render the TabPanel to Ext.getBody(). Does anybody know what might be causing this?

Try to set layout:'fit' on the tab.

BTW, I wouldn't render to a styled div, it can bring about problems that are hard to debug. Either render to Ext.getBody() or to a plain div: <div></div>.

[daveh0]

Tried adding layout: 'fit' to the just Tab 1 and to all three tabs - same result.

As far as rendering it to a styled <div> is concerned, I do not have the option to render it to the document body. I tried changing the html so that there are no style properties for the <div> it's being rendered to.

    <div id="ct" style="width:500px;height:400px;background:#fff;overflow:hidden;">
        <div id="int"></div>
    </div>

...same result.

[jsakalos]

Putting un-styled div in a styled one doesn't change anything. Styling a component by html attributes of its container it is rendered into is the least preferred method. Styles inherited from the container can collide with the component styles/css rules and an unpredictable look would result. If you need to style a conponent you can set cls or bodyCls config options and write css classes.

Try to render into <div id="ct"></div>. Another thing to try is to use html config option instead of contentEl (just to see if anything changes).

[daveh0]

ok, I tried rendering it to a completely unstyled <div> that is not nested within any styled elements:

<body>
    <div id="int"></div>
</body>

...same result. I tried setting the content via the html config option - same result. And I was mistaken in my original post. Rendering it to the document body does result in the same behavior.

I am stumped.

Does this work?

[daveh0]

yup

[jsakalos]

OK, so build upon it.

[daveh0]

well it seems that adding the style sheet before any of the <script> tags is the difference between what I had and what you just posted. Made the change in my file and it appears to be working.

Any idea as to why? (just so I can understand what's going on behind the scenes).
