Question

I have a horizontal box consisting of 4 other boxes separated by splitters. I want to use a splitter that looks like the tree-splitter (with no width), but whenever I try to use it, the splitters disappear and the columns cannot be resized. Any ideas why?

Or have you got any idea how I can implement a splitter that would look like one with id="folderpane_splitter" that has width probably 1px? This solution would be 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.

Answer 1

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.
