A couple question about GuiTreeViewCtrl

[DustyPorViva]

1) Can I collapse all nodes? For large trees it's annoying to have them all expanded when the tree is created. I tried:

PHP Code:

with (addnodebypath(i.name,"/")) {
  image = selectedimage = 2;
  expanded = false;
} 


But that didn't do anything. I even looped through all the nodes and used 'expanded = false' but still no luck

2) Can I delete a node?

3) How would I go about setting a custom image for a node, instead of the predefined ones?

Interestingly enough,

PHP Code:

function Test_Tree.onExpand() {
  player.chat = Test_Tree.expanded;
} 


and

PHP Code:

function Test_Tree.onFold() {
  player.chat = Test_Tree.expanded;
} 


both return true, which doesn't really make sense when folding a node. Also, if you try:

PHP Code:

Test_Tree.expanded = false; 


then the entire tree disappears, which would appear to be a bug unless it isn't intended to be used this way.

1) If that doesn't work to collapse a node, then I don't think there is a way.

2) node_object.destroy() should work.

3) You should be able to do it the same way as with GuiTextListCtrl:

PHP Code:

with (addnodebypath(i.name, "/"))
{
  icon.clearall();
  icon.drawimage(0, 0, "icon_image.png");
} 


node_object.icon is a TDrawingPanel, same as rows in a GuiTextListCtrl.

I'll admit I didn't try destroy(), so I'll test that out.

Also, I did try icon.panelstuff() to no avail. I'll give it another try, though.

Ya, icon.xxx() doesn't seem to be working

edit: nevermind, I just had to seticonsize() first.

For #1, instead of expanded, try using visible. It collapsed fine with visible.
For #2, use destroy().

visible worked great, thanks

All problems solved, I think... yey!
