Listbox, mouse selection problem

Recommended Posts

Friends,

I have written a program that among other things displays data in 3 listboxes. when the window has its original size, it works fine. But if I increase the size the window vertically the listboxes stretch as they should, and I can't select their top entries with the mouse Posted Image . The last listbox entries are not affected. The more I stretch the window vertically, the more entries become out of reach by the mouse. Also the highest entry that can be selected by the mouse is iffy. It has to be low on the entry.

But the keyboard arrow keys can select them with no problem.

The listboxes are resized with the window because of commands like

GUICtrlSetResizing ( $ControlHandle, $GUI_DOCKTOP + $GUI_DOCKSIZE + $GUI_DOCKRIGHT )

and that's probably where there is a problem with listview selection.

My OS is windows 2008R1, and I've tried this using both beta 17 and version 3.3.6.1, if that has anything to do with it.

Ideas anyone?

Here is the code to build a sample UI to reproduce the problem. It puts a list the folders into a listbox. Run it, try to select the top entries, then stretch the window vertically and try to select the top entries:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
Opt("GUIOnEventMode", 1)
Opt('MustDeclareVars', 1)
Dim $Win, $lblFolderList, $lbFolders
Main ()
Func Main ()
 $Win = GUICreate("Test Script", @DesktopWidth / 2 - 255, 188, 192, @DesktopHeight / 2 - 45, $WS_OVERLAPPEDWINDOW);$WS_SIZEBOX + $WS_MINIMIZE)
 $lblFolderList = GUICtrlCreateLabel("Folders List", 4, 8, 37, 17)
 GUICtrlSetResizing ( $lblFolderList, $GUI_DOCKLEFT + $GUI_DOCKWIDTH + $GUI_DOCKTOP )
 $lbFolders = GUICtrlCreateList("", 4, 24, 65, 168)
 GUICtrlSetResizing ( $lbFolders, $GUI_DOCKLEFT + $GUI_DOCKWIDTH + $GUI_DOCKTOP + $GUI_DOCKBOTTOM )
 GUISetState(@SW_SHOW)
 PopulateFolders()
 GUISetOnEvent($GUI_EVENT_CLOSE, "OnExit")
 GUISetState()
 While 1
  Sleep ( 1000 )
 WEnd
EndFunc
Func OnExit()
 Exit
EndFunc
Func PopulateFolders()
Dim $Search, $Found
Dim $InitDir = "C:\"
 GUICtrlSetData ( $lbFolders, "|" )
 $Search = FileFindFirstFile ( $InitDir & "\*.*" )
 if $Search > -1 Then
  While 1
   $Found = FileFindNextFile ( $Search )
   if @error Then ExitLoop
   If @extended = 1 Then
    GUICtrlSetData ( $lbFolders, $Found )
   EndIf
  WEnd
 EndIf
EndFunc

It's best to have a fully functional script that shows the problem, rather than a portion of it that someone else has to do a lot of extra work to make it run. I don't mean post your whole script, just a reproducer script that shows the problem.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

If you comment out the label and the resizing section of the script, it works fine. It might be that your label is overlapping.

      Hello all,
      I am trying to get scrolling events for ListBox (mouse wheel and up/down arrows) but without success. The event not occured on row change but if I click on it - yes
      The ComboBox works fine even if not in focus (with mouse wheel) but I prefer visual look of ListBox. In addition to all, I can't change the height of control. Unfortunately it depends only on font size and same fonts has different heights between InputBox and ComboBox
      Is there a way to get over the issue?
      Any other ideas for unit selection realization are welcome

      Hi, here are few functions for the ListBox.
      I have searched the forum, but most of the functions are for listview, so i took one example code from melba23 (clear selection) and
      wrote few more functions. (Because my current project needs them).
       
      These functions work only on a Multi-selection ListBox . 
      Edit: Only 1 function does not work with single selection box.
      The functions do: Clear Selection, Delete Selected items, Invert Selection, Move selected items up and down.
       The example code has 2 Listboxes. The selected items on the left ListBox can be moved up and down. The right Listbox has buttons for the other functions.
      #include <GUIConstantsEx.au3> #include <GuiListBox.au3> #include <WindowsConstants.au3> #include <Array.au3> Local $singlesel = 0, $iMsgBoxAnswer = 0 ;MsgBox features: Title=Yes, Text=Yes, Buttons=Yes and No, Icon=Question, Modality=Task Modal $iMsgBoxAnswer = MsgBox(8228, "Choose Listbox selecton type", "Yes for single, No for multi selection box") If $iMsgBoxAnswer = 6 Then $singlesel = 1 ;Yes Local $BL_1,$BL_2,$BR_1,$BR_2,$BR_3,$BR_4,$BR_5,$BR_6 Global $hForm1 = GUICreate("Listbox test", 349, 287) $LB_1 = GUICtrlCreateList("", 6, 40, 157, 244, BitOR($LBS_NOTIFY, $LBS_MULTIPLESEL, $WS_HSCROLL, $WS_VSCROLL, $LBS_DISABLENOSCROLL)) If $singlesel = 1 Then $LB_2 = GUICtrlCreateList("", 179, 40, 157, 244, BitOR($LBS_NOTIFY, $WS_HSCROLL, $WS_VSCROLL, $LBS_DISABLENOSCROLL)) Else $LB_2 = GUICtrlCreateList("", 179, 40, 157, 244, BitOR($LBS_NOTIFY, $LBS_MULTIPLESEL, $WS_HSCROLL, $WS_VSCROLL, $LBS_DISABLENOSCROLL)) $BR_3 = GUICtrlCreateButton("Reverse Sel", 272, 22, 68, 17) EndIf $BL_1 = GUICtrlCreateButton("Up", 20, 3, 35, 18) $BL_2 = GUICtrlCreateButton("Down", 60, 3, 35, 18) $BR_1 = GUICtrlCreateButton("Up", 200, 3, 35, 18) $BR_2 = GUICtrlCreateButton("Down", 240, 3, 35, 18) $BR_4 = GUICtrlCreateButton("Clear Sel", 217, 22, 52, 17) $BR_5 = GUICtrlCreateButton("Delete", 175, 22, 40, 17) $BR_6 = GUICtrlCreateButton("Populate", 290, 3, 50, 18) GUISetState(@SW_SHOW) For $x = 0 To 50 If $x <= 10 Then GUICtrlSetData($LB_1, $x & " test", 0) GUICtrlSetData($LB_2, $x & " Test", 0) Next While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit Case $BL_1 $a = Listbox_ItemMoveUD($LB_1, -1) If $a > -1 Then WinSetTitle($hForm1, "", "Moved items: " & $a) Case $BL_2 $a = Listbox_ItemMoveUD($LB_1, 1) If $a > -1 Then WinSetTitle($hForm1, "", "Moved items: " & $a) Case $BR_1 Listbox_ItemMoveUD($LB_2, -1) Case $BR_2 Listbox_ItemMoveUD($LB_2, 1) Case $BR_3 Listbox_ReverseSelection($LB_2) Case $BR_4 Listbox_ClearSelection($LB_2) Case $BR_5 Listbox_DeleteSelectedItems($LB_2) Case $BR_6 ;Populate GUICtrlSetData($LB_2, "") ; Clears the listbox For $x = 0 To 50 GUICtrlSetData($LB_2, $x & " Test", 0) Next EndSwitch WEnd ;note $hLB_ID - is the Listbox id Func Listbox_DeleteSelectedItems($hLB_ID) Local $aSel = _GUICtrlListBox_GetSelItems($hLB_ID) ;Get selected items Local $i, $slb = 0, $y, $x If $aSel[0] = 0 Then ;If the array is empty, there is no selection, or it is a single selection listbox For $x = 0 To _GUICtrlListBox_GetCount($hLB_ID) - 1 $y = _GUICtrlListBox_GetSel($hLB_ID, $x) If $y = True Then $slb = 1 _GUICtrlListBox_DeleteString($hLB_ID, $x) ;Perform a delete on single sel.

      Hi, 
      This is my very first post in this forum and am also new with Autoit programming so be easy on me.
      Below is the code that I am trying to get the index of the item selected. No problem getting the text.
      Case $listEdition   ; handle of the list             local $index=0             $item=GUICTRLRead($listEdition)    ; This will return the text in the list             ; ==============   The loop below always fails  ==================             ; Meaning _GUICtrlListView_GetItemSelected($listEdition, $i) always return FALSE. WHY ???????              For $i = 0 To $editionArray[0] - 1   ; The content of the list in an array where editionArray[0] contains total count of items                 If _GUICtrlListView_GetItemSelected($listEdition, $i) Then                     $index = $i                     exitloop                 EndIf              Next              ;===================================================             ConsoleWrite( "Select Edition:     " & $item & "  index: " & $index & @CR) ....... Please look at the comments in the code & the pix attached.
      _GUICtrlListView_GetItemSelected($listEdition, $i) always returns FALSE.
      Another problem is on the list. It also populate  the total count of items from the Array. How can I skip this item from populating to the list ?.
      Please advise and thanks

      Hello fellow coders.
      Im currently making a GUI for a webapp. Im using a REST API to get information and display this in a Tree view. Its basically a scheduler of "tasks" and these tasks are great to display in a tree view.
      The problem im having is that on some servers the tree can get rather large. So my GUI is reziable in ordet to be able to fit all the tasks in the view. I have then used GUICtrlSetResizing with diffrent options to get the GUI to look alright even when i resize it. It works fine an all GUI elements, except for the Tree-view. And if i remember correctly, the treeview item is another type of object and you cannot use regular GUI functions on it. Therefor im wondering of there are any alternatives?
       
      #include <ButtonConstants.au3> #include <GUIConstantsEx.au3> #include <StaticConstants.au3> #include <WindowsConstants.au3> #include <GuiTreeView.au3> #Region ### START Koda GUI section ### Form= $Form1 = GUICreate("Form1", 208, 220, 192, 124,$WS_SIZEBOX) $idTV = _GUICtrlTreeView_Create($Form1, 4, 25, 200, 140) GUICtrlSetResizing(-1,$GUI_DOCKMENUBAR) $Button1 = GUICtrlCreateButton("Button1", 8, 168, 75, 25) GUICtrlSetResizing(-1,$GUI_DOCKSTATEBAR) $Text = GUICtrlCreateLabel("Text", 8, 8, 25, 17) GUICtrlSetResizing(-1,$GUI_DOCKMENUBAR) GUISetState(@SW_SHOW) #EndRegion ### END Koda GUI section ### While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit EndSwitch WEnd This code is an example of my problem (run it and try to resize the window). If anyone has any ideas i would appreciate it
