Hide Tree Control Selection

[raphschru]

Hi fellow developers,

When clicking on a tree control item during runtime, a blue selection displays the currently selected item.

Is there any way to disable/hide that (annoying) selection? I find it a bit ugly and its behavior seems a bit inconsistent, which is frustrating for the user.

I cannot make it an indicator otherwise the cells cannot be edited by the user anymore.

Also, when clicking somewhere else in the tree, the last selection remains visible with a dotted outline, which I don't want either:

The only way I see would be to use the filter event "Mouse Down?" with the discard option and recode the logic for all the clicking interactions (edit cell, right-click menu, double-click, open/close item, ...). I started this way, but this is ridiculously complicated!

Also, making the selection transparent does not help...

I hope there is a simpler way...

Thanks in advance,

Raphaël.

After you've done whatever processing you need after a value-change, or mouse event, simply set the value to -1.

I guess you meant set the tree value to an empty string?

I managed to reduce the appearance of the blue selection by setting the tree value to an empty string at "value change" of my tree.

Note : I am also using the "Mouse Down?" event to allow the user to edit the cells more rapidly by controlling the edit position:

However, there is still the dotted outline and the blue selection occasionally flashes very briefly:

Adding another reset of the tree value in the "Mouse Down?" or "Mouse Down" event handlers has no additional effect.

I had also tried playing with "Defer Panel Updates" without success.

You can eliminate the blue flashes by changing the selection color to white.

You can somewhat reduce the dotted frame by removing key focus on a Mouse-leave event.
