Hello Support ,
I want to set a different visual styles for columns in the VirtualTree.
Especially it's important for Main Column Background style .

Thanks a lot .

You can set styles for Columns using the Virtual Tree designer. Simply select the column(s) and set the properties of the CellStyle. This will apply the style to the whole column.

Hi,
The problem is that it doesn't paint the Expand and Collapse Area (And the tree lines!) See screenshot

The cells in the main column start after the expansion indicator. The style of the area before this is controlled by the VirtualTree.RowStyle. You could set this style as required then modify the styles of the other cells. I can see that this may be a little incovenient in your case where you are trying to set the background of the entire column. This is an issue we will take a look at to see if we can change.

We have reworked the RowWidget and CellWidget drawing code in Version 3.12.0 (just released) so that now you can set the background of the whole main column by setting the Column.CellStyle.
