TreeView - editable?

[ReFran]

Hi,

I work on GUI for PDF handling. For to set up the bookmarks I work with a TreeView. Reading in the bookmarks from a PDF works good and looks good in the TreeView. Now, for writing, it would be fine if the bookmarks would be editable direct in the treeview.

I saw an example how to edit an ListView. But I didn't find anything find for TreeView.

Is that not possible? Any workaround?

Best regards, Reinhard

some constants needed

Global Const $TV_FIRST = 0x1100

Global Const $TVS_EDITLABELS = 0x8

Global Const $TVGN_CARET = 0x9

Global Const $TVM_GETNEXTITEM = ($TV_FIRST + 10)

Global Const $TVM_EDITLABELA = ($TV_FIRST + 14)

Global Const $TVM_ENDEDITLABELNOW = ($TV_FIRST + 22)

Start the edit

$h_item = GUICtrlSendMsg($treeview, $TVM_GETNEXTITEM, $TVGN_CARET, 0)

GUICtrlSendMsg($treeview, $TVM_EDITLABELA,0,$h_item)

the edit control is the same as ListView "Edit1"

Cancel Edit

GUICtrlSendMsg($treeview,$TVM_ENDEDITLABELNOW,True,0)

I think you can probably figure out how to update based on what was done for the ListView

Edit: check scripts and scraps

here's a quick modification to the example from the help file

selet about under general, type in new text and press enter

Hi Gary.

I don't now what I should write. It works GREAT!.

After some searching I though already I would have to use for the bookmark part a third party freeware. But with your example I can write it by myself in the way I like it.

Sometimes I should try to understand, where the "Const" come from and the use of it. I didn't find "$TVS_EDITLABELS". But at time I'm simply very happy that I've a solution.

Thanks for it, Reinhard
