How To Clear ListView ToolTips?

3 posts in this topic

Hey all,

Hopefully an easy question...if I have a listview with tooltips enabled and I move the mouse cursor off the listview, how can I clear the tooltip? In the reproducer below, the tooltip remains in almost every circumstance - even if I minimize the gui, the tooltip still overlays other windows. I'd like it to be cleared if I'm outside of the listview, ideally.

Thanks.

For $i = 0 To 5
    GUICtrlCreateListViewItem(StringFormat("Item %s|abc%s|def%s", $i, $i, $i), $idListView)
Next

Hi.  maybe this.

      Hi I need help with the code bellow, my goal is to make faster sqlite queries to Sqlite because _SQLite_GetTable2d seams to be slow on big tables.
      Thank you :
       
      https://www.autoitscript.com/forum/topic/182469-using-controls-to-edit-cells-in-a-listview/
       
      Well my code is faster but a I have 2 issues :
      1 Memory leaks
      2 Listview ( virtual) a little slow when scrolling (column headers delay )
      Please help I am not a WinApi specialist. (The hugetable its actuality much bigger I'm limited by upload size)
      Thank You.

      I would like to hide the header in the listview, but I did not find anything in the help and in the forum, you have some advice, thanks.

      Hi there,
      I have a small hopefully quick fixable issue with reading information from my ListView:
      So in fact I just want to have information about which items are selected, so I'm using
      msgbox(0 , "return", GUICtrlRead($myListView), 1)
      but unfortunately it only returns me either the first item id or if this is not selected the second item id, or if this is not selected the third, etc. or 0 if none is selected.
      Anybody has an idea how to get the full picture of my >>multiple Items selected<< ListView?
      Thanks in advance!

      Hi guys! How are you? Hope you're fine
      I'm trying to use SQLite for managing some data, and, I would like to display my "retrieved" data, but I'm trying to do a select from 2 table, and seems to not work properly...
      What I'd like to do is retrieve data from 2 tables and display in a listview...
      I tried with:
      Local $aRisultato, $iRighe, $iColonne, $iRVal $iRval = _SQLite_GetTable2d($hDatabase, "SELECT * FROM Magazzino_Rockwell, Magazzino_Siemens;", $aRisultato, $iRighe, $iColonne) If $iRVal = $SQLITE_OK Then ;_SQLite_Display2DResult($aRisultato) _ArrayDisplay($aRisultato) EndIf ... but it displays a single record 41 times, and it does this thing for every record in the database...
      What do you need to help me?
      Thanks  

      EDIT:
      Managed with a double If and double query like this:
       
      $iRval = _SQLite_GetTable2d($hDatabase, "SELECT * FROM Magazzino_Rockwell;", $aRisultato, $iRighe, $iColonne) If $iRVal = $SQLITE_OK Then Local $aRisultatoRockwell = $aRisultato $iRval = _SQLite_GetTable2d($hDatabase, "SELECT * FROM Magazzino_Siemens;", $aRisultato, $iRighe, $iColonne) If $iRVal = $SQLITE_OK Then _ArrayConcatenate($aRisultato, $aRisultatoRockwell) Local $i, $sRiga, $s_LV_Item For $i = 1 To Ubound($aRisultato) - 1 $sRiga = $aRisultato[$i][0] & "|" & _ $aRisultato[$i][1] & "|" & _ $aRisultato[$i][2] & "|" & _ $aRisultato[$i][3] & "|" & _ $aRisultato[$i][4] & "|" & _ $aRisultato[$i][5] & "|" & _ $aRisultato[$i][6] & "|" & _ $aRisultato[$i][7] & "|" & _ $aRisultato[$i][8] & "|" & _ $aRisultato[$i][9] & "|" & _ $aRisultato[$i][10] & "|" & _ $aRisultato[$i][11] $s_LV_Item = GUICtrlCreateListViewItem($sRiga, $lv_Lista) Next And so, the listview is created
      If anyone has another more efficient way, I'm here Thanks guys
