TreeGadget : optional image parameter ?

[eddy]

OpenWindow(0,0,0,240,210,#PB_Window_SystemMenu|#PB_Window_ScreenCentered,"TreeGadget")
CreateGadgetList(WindowID())

#GADGET_Explorer=1
TreeGadget(#GADGET_Explorer,0,0,100,100,#PB_Tree_AlwaysShowSelection)
;First Item
LoadImage(#GADGET_Explorer,"img\new.ico")
AddGadgetItem(#GADGET_Explorer, -1, "Item with image",ImageID())

;Sub Item
OpenTreeGadgetNode(#GADGET_Explorer)
AddGadgetItem(#GADGET_Explorer, -1, "Sub Item")
CloseTreeGadgetNode(#GADGET_Explorer)

Repeat
Until WaitWindowEvent()=#PB_Event_CloseWindow

Why sub-item uses the last loaded image ?
I specified no image.

Once you add an image, all Items need images, that's the way it works.

is it a global style for all of the tree ?

Hi Eddy,


try to put a negative value for ImageID

AddGadgetItem(#GADGET_Explorer, -1, "Sub Item")

But as Freak said it, Once you add an image, all Items need images, that's the way it works. So, with a negative value under Win98, no image is displayed but the system put space between horizontal line and text.

Ok I understand.

The problem is that even if I use a tiny image, Win$ stretches it to fit a common size. :roll:

[freak]

This is a Windows thing, not a PB one:

To add an image, there is an ImageList created, and so all Items get an
Image from that list. That's why all must be (or are streched) to the same
size. If you put a negative value (which is an invalid ImageID()), there
is no image to display, but Windows puts these spaces there.

There is no way to change that, sorry.
(It's the same with Checkboxes. You can have either checkboxes on all
items, or on none of them)
