Hello!

I am now using the TreeTable to display a tree table. I have a simple question. Is there a way to have the header be images rather than text(strings)?

I looked around (in the TreeTable/AbstractTreeTableModel source and the simple.xml theme file). I do not see anything that would allow me to change this.

It looks to me that this takes only Strings because in the TreeTableDemoDialog1 demo, there is a method on the MyModel class that is called: getColumnHeaderText() which returns only a String.

If this support does not exist, I would like to request it

Thanks.

You can implement it the following way:
1) Override getColumnHeaderStates() in the model to return an additional unique StateKey for each column like this:
2) Override getColumnHeaderState(int column, int stateIdx) to return true for the respective column state like this:
This will result in column 0 having the animation state "column0" active, while column 1 has "column1" active.
Now you can assign the column header buttons a <select> image object (as overlay) which decides based on these states which image/icon to show.
