Hi All,

Can anyone tell me if it is possible to edit tree gadget items? IE have a button to press to edit the selected tree gadget item

Thanks for reading

For Windows you may take a look into this almost 12 year old tutorial from freak (updated for PB 5.20)...

Hi Craig. As Shardik had pointed out, freak's method is ultimate. However, if you might prefer a non-API, cross-platform solution, try this one:

I've streamlined my earlier solution to require only two parameters instead of three, and to do away with the enumeration block. To implement it in any project that requires editing capabilities for the TreeGadget(), simply add this procedure, and then call it with the tree gadget number, and its parent window number.

just add this procedure to your project:

Code: Select all

;=============================================================
; fully self-contained and ready to use - no changes required.
; just drop into your project and call ediTree(win#, tree#)
;=============================================================
Procedure ediTree(parentWindow, treeGadgetNo)
  DisableWindow(parentWindow, #True)
  treeText.s = GetGadgetText(treeGadgetNo)
  
  treeEditor = OpenWindow(#PB_Any, DesktopMouseX(), DesktopMouseY(), 100, 20, "", 
                          #PB_Window_BorderLess, WindowID(parentWindow))
  AddKeyboardShortcut(treeEditor, #PB_Shortcut_Return, 1)
  AddKeyboardShortcut(treeEditor, #PB_Shortcut_Escape, 2)
  teString = StringGadget(#PB_Any, 0, 0, 100, 20, treeText)
  SetGadgetColor(teString, #PB_Gadget_BackColor, RGB(255, 255, 0))
  SetGadgetColor(teString, #PB_Gadget_FrontColor, RGB(100, 0, 0))
  SetActiveGadget(teString)
  
  Repeat
    Select WaitWindowEvent()
      Case #PB_Event_Menu
        Select EventMenu()
          Case 1
            If Trim(GetGadgetText(teString)) <> ""
              SetGadgetText(treeGadgetNo, Trim(GetGadgetText(teString)))
            EndIf
            escaped = 1
          Case 2
            escaped = 1
        EndSelect
    EndSelect  
  Until escaped
  
  DisableWindow(parentWindow, #False)
  CloseWindow(treeEditor)
  
EndProcedure

and place the call inside the PB_EventType_LeftDoubleClick event of the tree gadget:

Code: Select all

ediTree(windowNumber, treeGadgetNumber)

That's all!

@TI-994A , Very nice solution.

Thank you for sharing.

Thank you, TI-994A and Rashad for your nice examples!

RASHAD wrote:Color not supported in MAC

The color constants #White and #Black in your code are only defined in the Windows version. But a simple

Code: Select all

  CompilerIf Defined(White, #PB_Constant) = #False
    #Black = 0
    #White = $FFFFFF
  CompilerEndIf

at the top of your code will allow your example to be also executed on Linux and MacOS X (tested on MacOS X 10.9.5 "Mavericks" x86, Ubuntu 12.04 x64 with Unity and Windows 7 SP1 x64 )...

Unfortunately you have to really test a seemingly cross-platform solution on all 3 operating systems to really be sure because even without any API functions there seem to exist subtle differences between the platforms. In both your examples you have to change

Code: Select all

SetGadgetText(treeGadgetNo, Trim(GetGadgetText(#teString)))]

to

Code: Select all

SetGadgetItemText(treeGadgetNo, GetGadgetState(treeGadgetNo), Trim(GetGadgetText(#teString)))

in order to finally display the edited node text in the TreeGadget on MacOS X 10.9.5 "Mavericks" (no problem with your original line on Ubuntu 12.04 x64 with Unity and Windows 7 x64 SP1, but the modified line works correctly on all 3 platforms)...

@davido: Thank you.

@Shardik: Thank you, and also for pointing out the compatibility issues with Mac OSX. I must admit that it was only tested on Windows; like the listing says, quick & dirty.

Nevertheless, it might be worth putting a note to the documentation team, highlighting this incompatibility with the SetGadgetText() function when used with the TreeGadget() on Mac OSX.

@Rashad: Good approach habibi, although scanning for the highlight colour would not work when custom colour preferences or themes are applied. Also, the string gadget gets displaced if the list is scrolled during editing, and it gets clipped if the tree gadget width is smaller than the tree.

I've taken a page from that approach, and modified my example to retrieve the currently applied highlight colour using the Windows GetSysColor() API function. To maintain cross-compatibility, I've added a compiler directive to implement the original method on Mac OSX and Linux.

Hi RASHAD. Really nice! But there appears to be something wrong with your example; the first double-click displays the string gadget for editing, but not on consequent clicks. Also, the displacement issues are still there; the string gadget doesn't scroll with the tree, and it gets clipped by the scroll bar if the tree gadget width is smaller than the tree width.

I've implemented this approach in my example. Please note that the edit activation sequence has been changed from a double left-click to a single right-click followed by a single left-click, so that it would not interfere with the tree expanding/collapsing action which also uses the double left-click sequence.

Hello again. You've solved the clipping issue with the string gadget, but it still does not scroll with the tree. Also, the first double-click to activate the editing works, but not consequent ones; the string gadget simply doesn't appear.

I've just tested my code with PureBasic v5.30 on Windows 8.1, and it works exactly as it should. What are the issues that you seem to be facing? Perhaps you didn't realise that I changed the editing activation sequence.
