Relative width of Parts in PartSashContainer - containerData has no effect [message #1115768]

I'm creating a RCP e4 application product and want to set the initial width of two Parts in a horizontal PartSashContainer.

I read about just setting the containerData attribute of the Parts, e.g. "20" and "80" for a 20% to 80% relation. I'm just doing this but it doesn't have any effect on the actual rendering. The Parts have equal widths.

That's the appropriate code in the XMI:

<children xsi:type="basic:PartSashContainer" xmi:id="_YtXj4CUhEeO-E52C3JQ7OQ" elementId="my.partsashcontainer" containerData="" selectedElement="_-W9m8CUXEeO-E52C3JQ7OQ" horizontal="true">
      
	<children xsi:type="basic:Part" xmi:id="_-W9m8CUXEeO-E52C3JQ7OQ" elementId="my.part1" containerData="20" contributionURI="bundleclass://my.app/my.part1" label="Part1"/>
      
	<children xsi:type="basic:Part" xmi:id="_joYXsCE2EeO-E52C3JQ7OQ" elementId="my.part2" containerData="80" contributionURI="bundleclass://my.app/my.part2" label="Part2"/>
    
</children>

(The product is an org.eclipse.fx.ui.workbench.application, if that's of any interest.)

Or put the part in partStak and set the containerData of the PartStack and it should work.

Thanks for your quick answers, but none of the approaches has an effect. Sad

It works for me.

That's what I feared. Sad

I just had a look at the sample project from E(fx)clipse Tutorial 4 which has a similar application model.

PartSashContainer
-Part(containerData="0.3")
-Part Stack(containerData="0.7")

If I run the project, the Part and the Part Stack have nearly equal size, the ratio is roughly 45% to 55%.

Why doesn't this work in my environment?

I'm using Eclipse Kepler with e(fx)clipse IDE 0.9.0.201309190708 and e4 Tools 0.14.0.v20130814-1230 with jdk1.7.0_25 on Windows 7 64bit.

Are you using SWT or efxc renderers? If it's the second I'll move this to the efxc forum.

Also, if the sum of the widths is too small you'll see choppy drag behavior because changing the value from '80' to '75' for example will cover many more than 5 pixels.

Generally you should keep the totals fairly high (i.e. we'd use 8,000 / 2,000 as the sum so that we have plenty of room rather than 80 / 20.

Hi,

OK - this is a freaking FX-SplitPane problem. The reason is that the
first layouting happens BEFORE the stage is show and has a size.

Now when we try to apply the sash weights can not be smaller than the
minimal content and because of that the split is roughly 50:50.

I've filed https://bugs.eclipse.org/bugs/show_bug.cgi?id=417965 and
fixed it with
http://git.eclipse.org/c/efxclipse/org.eclipse.efxclipse.git/commit/?id=b7bdb71360564bc2aba13ba5eaf54c5000cb6d6f
so the next nightly build should hold it. You don't need to update the
tooling BUT you need to reset your target-platform to the nightly build.
