Hi everyone,  
I am trying to implement a custom layout very similar to SlicerLayoutFourUpQuantitativeView.  
However, I would like to set a minimum width/height to views so that when the user stretches one views others do not disappear.  
Is there already something existing to do that ?

Thanks in advance,  
Cheers

Pierre

Probably not possible as of now

For instance: def formatCustomLayout(self): customLayout = ( XML code ) layoutNode = slicer.app.layoutManager().layoutLogic().GetLayoutNode() customLayoutId = 500 layoutNode.AddLayoutDescription(customLayoutId, customLayout) slicer.app.layoutManager().setLayout(customLayoutId) slicer.app.layoutManager().sliceWidget('Long2').mrmlSliceNode().SetDimensions(100, 100, 1) #end format…

The proper solution would be to add attributes for this in CTK (in [ctkLayoutManager](https://github.com/commontk/CTK/blob/master/Libs/Widgets/ctkLayoutManager.cpp#L431)). But if you have never used C++ then you can work around this in Python by looking up the widget using [`slicer.util.findChildren`](https://slicer.readthedocs.io/en/latest/developer_guide/slicer.html#slicer.util.findChildren) and adjusting sizing properties.

Thanks Andras,  
Do you know if there is a way to fix the size at layout creation  
I tried to use verticalStretch="0" horizontalStretch="0" but it was not working

> \<item splitSize="300"\>"  
> " \<view class="vtkMRMLViewNode" singletontag="1" verticalStretch="0" horizontalStretch="0"\>"  
> " \<property name="viewlabel" action="default"\>1"

There are no such properties implemented in [ctkLayoutManager](https://github.com/commontk/CTK/blob/master/Libs/Widgets/ctkLayoutManager.cpp) as `verticalStretch` and `horizontalStretch`. You can search for `.attribute` in the file to see what properties are available. You can modify this file to add support for more attributes.

This is probably a small issue but in [Slicer/vtkMRMLLayoutLogic.cxx at 81ff76b24d4913dbd992b7eed4d77805f306ffe8 · Slicer/Slicer · GitHub](https://github.com/Slicer/Slicer/blob/81ff76b24d4913dbd992b7eed4d77805f306ffe8/Libs/MRML/Logic/vtkMRMLLayoutLogic.cxx#L54), verticalStretch is defined
