Seems to be impossible to add an icon to a ListView Item !

Recommended Posts

Rickname

I am trying to add a specific icon or image to a specific ListView Item . I add the items in the ListView control with this command : _GUICtrlListView_AddItem .

Right now what I only managed to do is to add an icon for ALL the items in the control, BUT, if I try to add an icon to only one item , its just impossible :( Atleast for me >_<

I have tried GUICtrlSetImage(-1, "C:icon.ico") tried with creating _GUIImageList_Create , icons not transparent , 16x16 pixels, tried many other icons, tried with .bmp, .png - nothing worked so far O_O !

Anyone yet managed to do something with this problem so far? :blink::( Thanks :)

How about posting your code, so we can see what you're doing? Otherwise we have to first guess at what you have thus far, and then try to troubleshoot it. ;)

Nvm, I managed myself :) The problem was that the picture must be either .bmp. either .ico type.

The source code I used :) :

#include <WinAPI.au3>
#include <GuiListView.au3>
#include <GuiImageList.au3>
#include <WindowsConstants.au3>
#include <GuiConstantsEx.au3>
#include <GuiListView.au3>
#include <GuiImageList.au3>
#include <Constants.au3>
#Include <WinAPI.au3>
_Main()

Func _Main()

    GUICreate("ImageList AddBitmap", 400, 300)
    $listview = GUICtrlCreateListView("Items", 2, 2, 394, 268)
    GUISetState()

    ; Load images
    $hImage = _GUIImageList_Create(32,32)
    _GUIImageList_AddBitmap($hImage, "C:\pic.bmp")
    _GUICtrlListView_SetImageList($listview, $hImage, 1)

    ; Add items
    _GUICtrlListView_AddItem($listview, "Item 1", 0)

    ; Loop until user exits
    Do
    Until GUIGetMsg() = $GUI_EVENT_CLOSE
    GUIDelete()
EndFunc   ;==>_Main

      hello Im wondering if it is possible to process image in autoit like this
      1. firstly there is colorfull wallpaper
      2. Fill all colors (exception rose color) - with white
      3. Fill rose color with black color
      I see Gdi functions have things to manipulate images

      GdipBitmapGetHistogram(), GdipBitmapGetHistogramSize() and 2 more GDI+ functions requires GDI+ v1.1 which means this will only run on Vista or higher operating systems.
      I hope the values are correct especially the value for luminosity.

      Im wondering if its possible to read pixel colors from not only from top window.
      For example I got a few windows with images how (in attachment video) . Is it possible to read pixel color for example 200px, 200px from top left ?
      Can i make something like winlist for the same window names and then get handles for every listed exact name window and then read for every window pixel color for example: 200px, 200px from top left ?

      Is there a (simple) way to make your script using a picture-control to resize the gui?
      This would be useful for a transparant pop-up window with a custom made theme using picture controls:
      $Form = GUICreate('', 301, 173, 5, 5, $WS_POPUP, BitOR($WS_EX_LAYERED, $WS_EX_TOPMOST)) GUICtrlCreatePic(@scriptdir & "\resize_win.bmp", 0, 73, 20, 51) ; some api call or code telling the os to use this picture as a resize border GUICtrlSetResizing(-1, $GUI_DOCKLEFT+$GUI_DOCKTOP+$GUI_DOCKBOTTOM+$GUI_DOCKWIDTH+$GUI_DOCKHEIGHT) GUISetState(@SW_SHOW) While True if GUIGetMsg() = $GUI_EVENT_CLOSE then Exit WEnd  
      EDIT: to make it more clear what i wanna do, if you go with the mouse arrow over the border of a re-sizable window the arrow changes to a "resize" arrow, you click and drag the border and then the window size adjusts to the mouse position until you release the mouse button.
      I want my picture control to be used the same way as the resize border to resize my window.
