Detect ListView Item delay click

Recommended Posts

Hi,

i try to simulate the $LVS_EDITLABELS behaviour so by clicking twice the item can be edited but the second mouse click has to be a little bit delayed to trigger the editing. The editing has to be done in other columns too, so i can't use $LVS_EDITLABELS.

So

- one click selects an item

- double click performs a specific function

- one click + another 800ms delayed click performs an editing

Does someone have an idea?

Trolleule,

Why not just use a modifier key to distinguish between a "normal" and "delayed" doubleclick cases? That way you can use the same handler to detect the doubleclick and then use _IsPressed to look for the modifier key and adjust the resulting action accordlingly.

Sure, but i got it. Now i try to select/mark the text in the edit control, but it seems impossible. I will open a new thread.

Thanks for your thoughts!

I think you will building a UDF for editing each Item in a LV. Why not using a already writen UDF, @Melba23 and @Kanashius have oublished one on autoitscript @BugFix and @Kanashius have published one on autoit.de. This 3 UDF's are surely not the only one, but i think the top 3. In https://autoit.de/index.php/Thread/12137-Perle-f%C3%BCr-alle-LV-Benutzer-gefunden-muss-aber-noch-poliert-werden/  i introduce a UDF (from Gary Frost) which integrats also DateTimePicker, ComboBox and ProgressBar by using callback.

hey AutoBert,

thanks for this inspiration. This example helds some really nice tricks, I grant, but sorry...the code is a piece of shit! The code has made me angry, the implementation is horrifically, but i have learned by watching.

The sub-title i give the thread is not correct: "must be polished first" => "must be rewriten" would be better. I used this 4. udf in a project with several LVs i full acknodledge.

      good morning all.
      first lit me give you all a thinks to your help
      you're help me allot thank you all.
      sirs today i've a new problem
      it's not a problem but thing i want to add it to blind accessability.
      the ListBox can send a notification when the user send a double click on it items
      but as we know that the blind users can't use the mouse for that they use the keybord to navigate.
      as we know that the enter replace the double click on the keybord
      for that i need when the user send a inter above any listBox item the list send a double click notification.
      i know some of you tell me that i can use the  GUISetAccelerators function
      but the enter has a other tasks such as leav a blanc line on edits and activate the defaultButton and other tasks.
      that what i need and i hope that you can help me
      this is a simple example.

      Hey there!
      I am having a problem with clicking a button in IE. As you can see in the code, there would be a class name to click it, but since this button exists several times with exactly the same code, I can only use the "Noch nicht veröffentlicht" to separate it from the others. But this part is just pure text without any classification. 
      "<div class="checkmark" data-v-1e5b1f70=""><svg xmlns="http://www.w3.org/2000/svg" class="icon" viewBox="0 0 16 16" data-v-1e5b1f70=""><circle cx="8" cy="8" r="8" data-v-1e5b1f70="" /></svg></div>Noch nicht veröffentlicht"
      I was trying to click it with:
      #include <IE.au3> local $oNNVs = _IEFormGetCollection($oIE2) For $oNNV in $oNNVs If String($oNNV.innertext) = "Noch nicht veröffentlicht" Then _IEAction($oNNV, "click") EndIf Next and:
      $inputs = $oIE2.document.getElementsByTagName("div") For $input In $inputs If $input.innertext == "Noch nicht veröffentlicht" then $input.click() EndIf Next But nothing seems to work. Thanks for the help!

      Greetings!
      I am in need of your guidance once again. I searched the forums for clicking in span, clicking by class, clicking without an ID or Name, etc., but I am unable to find a solution for my problem.
      I am trying to expand this tree in IE. There is an arrow ( > ) that i need to click, but I can't find a way to do it . Alternatively, I can double-click the text "Servers", but that seems to be even more troublesome. I will have to do this 2-3 more times as the tree expands.
      There appears to be an ID for the tree, simply called "tree", but that isn't working when I send a click to it.

      ;Open an IE session and navigate to pgAdmin. Global $oIE = _IECreate($pgAdmin) ;Maximize the IE window. WinSetState(_IEPropertyGet($oIE, "hwnd"), "", @SW_MAXIMIZE) Sleep(2000) ;Expand the tree $oTree = _IEGetObjById($oIE, "tree") _IEAction($oTree, "click") Any ideas?
