TElXTree: Multi-Selection: Ctrl+Click doesn't deselect a selected item

RaymondWK

The standard behaviour in Windows is to use Ctrl+Click to select and deselect an item.

That doesn't happen with TElXTree.

One of the issues is that the Focused item is selected.

Is there a setting for this?

Would you consider making this change in the source code?

Thanks.

When? Which settings? You should describe exactly when this case happens.

This is standard in TElXTree as well (when MultiSelect is enabled).

If you mean different behaviour when Ctrlkey is pressend and arrow keys are used fr navigation: Then this is by design.

None of my ElXTree controls deselect any rows.

However, the following illustrates other problems with the selection process.

Consider the ElXTree 5 Demo.

Choose the Controls demo.

Click the first row to both Select and Focus it.

Keep the Ctrl key down and click on the row again and again and again. After a while nothing changes.

Click on another row and click the same row again. Nothing happens.

Also, if you select a single row and then Ctrl+Click on it in the same location, then it is not deselected.

Also, select a row, then a 2nd row. Now deselect the 2nd row and try to select it again. Nothing happens for several Ctrl+Clicks and then just the cell becomes highlighted, and sometimes this highlight only appears after Ctrl+Click on another cell.

So some things are clearly and reproducibly wrong.

I will try to create a demo in which no rows can be deselected by Ctrl+Click, but only after you have tried the steps above on your own demo and fixed those problems first.

Please let me know if you are able or not able - either way - to reproduce the problems I have provided steps for, as this might make it unnecessary for me to create a further demo.
