Hi

My problem is TreeViewer, i have been created LabelProvider and ContentProvider. I get some correct data on my treeviewer. I have been initialized my Treeviewer like this TreeViewer(SWT.CHECK);

This way i can get checkboxes on my treeviewer rows.
But i want to show checkboxes only parent rows, like this

 _ 
I_I Parent
      Child
      Child
       _
      I_I Parent
            Child
            Child

I hope that u guys get what i wanted to do and you can help me with this.

Kokkonen,

To my knowledge, the native Tree control (and by extension TreeViewer
and CheckboxTreeViewer) does not support this.

You may want to take a look at the Nebula Grid control and see if it
does what you need.

http://www.eclipse.org/nebula/widgets/grid/grid.php

FYI, the Grid control is supported on the eclipse.technology.nebula
newsgroup.

Hi

Ok it seems that i have to play with images.

Well i try this image fake solution and it works, BUT now i have only one image and it is checked or unchecked image.

Problem is that i want to put at least two images on same row.

I try to put TreeViewerColumns but when i open nodes only first column was indented, so when i open nodes first column get's under second column and disappears.

Anykind of solutions for this problem is welcome!!

Hey Kokkonen,

I've never done this for trees, but I would try to subscribe to paint events and then draw the images into the first row. If that is an option for you, have a look at this link: http://www.eclipse.org/articles/article.php?file=Article-Cus tomDrawingTableAndTreeItems/index.html
