Implementing splitter with no width inside a box

Question

Hi,

I have horizontal box consisting of 4 other boxes separated by splitters. I want to use splitter that looks like the tree-splitter (with no width), but whenever im trying to use it splitters dissapear and the collumns cannot be resized. Any ideas why? Or have you got any idea how can I implement a splitter that would look like one with id="folderpane_splitter" that has width probably 1px- this solution would be just perfect for me.

My code looks like:

<hbox>
     <hbox flex="10">
         <label value="name1"/>
     </hbox>
     <splitter/>
     <hbox flex="20">
         <label value="name2"/>
     </hbox>
     <splitter/>
     <hbox flex="30"">
         <label value="name3"/>
     </hbox>
     <splitter/>
     <hbox flex="40">
         <label value="name4"/>
     </hbox>
</hbox>

If anyone wonders I'm working on an extension for Thunderbird. Thank you very much in advance ;)

Answer 1

I tried using the id="folderpane_splitter" in firefox but it didn't change look. Anyway perhaps you are looking for something like this?

<splitter style="-moz-appearance: separator;"/>

Answer 2

Using:

<splitter style="background-image: none; width: 1px; min-width: 1px;"/>

gave me the apperance I needed. Probably not overriding min-width was blacking it from getting thinner.

Answer 3

Trees have special code to make zero-width splitters work.
