Hi Derek,

As usual, you have produced something VERY simple and VERY useful.
Thank you very much..............

I think it's a great feature to use in table grids at my end.

Hi Adam, Jean, Sparrow,
I was having a think about this project of Adam's and wanted to see how far you could get with (almost ) no script).
Have a look at the attached as a possibility.
Click on the combobox to select an icon and then simply click in the first column of however many rows you want to highlight (change the combobox selection for a different icon etc or choose the first empty row of the combobox to remove any highlighting).
Advantages
1. very small script
2. nothing is hard coded so new icons can simply be added by clicking on the 'configuration' button on Form1 which makes it pretty flexible.
Disadvantages
1. although it is still a 'tree', you lose the vertical and horizontal lines that better display the child nodes.
Maybe someone will find the approach useful.
Regards,
D.

Blame it on old age! Or I might have uploaded the wrong thing and then quickly deleted it.
Either way, download this attachment to make sure you've got the right thing.
When you run it, just click on the '⚫' to toggle highlighting.
Derek.

Hi JB,
Thank you very much.....

What I was looking for adding / removing an icon to a selected node on user level, perhaps using combobox.

Hi Derek,
Thanks a lot....... I'll check it out.

I had a quick look. It will be useful in some cases, but what I was looking for ico/image like in JB's example but adding/removing on user level.

Hi Adam, Salut Jean,
Ça va ? Il fait très chaud en France en ce moment, je pense! Reste cool!
I'm guessing that you just want to use an icon as a toggle - simply click it to mark a node in the tree as requiring attention and then click the icon again when you're done with it.
I just used unicode symbols rather than true 'icons' as I always like to keep the scripts as short as possible.
Maybe try something like the attached (I've used 'color' to highlight nodes rather than 'bold' but the principle is the same).
Regards,
Derek.

Hi Derek and all,

Derek, Once again, thank you very much for your kind help.

Taking customizing TreeView further, would it be possible to add on the left of tree node custom icon/image and changing selected tree node text font + font size permanently until user changes them?

Hi Adam,
Try doing it something like the attached (I went with 'colour boxes' in the end rather than a button or a right-click). It just seemed more intuitive.
But if you have a large number of colour options rather than just a few, maybe use a combobox instead (the same logic applies).
Regards,
Derek.

Hi Derek,

Thank you very much......

I'm sorry, I think I wasn't clear enough about my question.
What I was looking for applying color/style to a selected node permanently, until it's changed by the user, not a selection highlighting.
For instance, I like to color a node text on treeview blue and bold, and another node color red. Remaining nodes stays default text / style defined in prosperities of the treeview. I'm hoping to find a way to customize treeview bit further.

After introduction of the treeview, I asked to Dmitry about customization of the treeview such as adding custom icons and changing node text coloring / size / style, If I remember correctly he said they are in the to do list. Unfortunately, he left before getting around doing them.
