Double Click - Right Click In A List Example

 Share

Recommended Posts

I made this example to have here when I need it and to share. I took some code from other examples and put together a new example of using doubleclick and rightclick in a list box in hopes someone might understand it better all layed out in one simple example. If you see your code hop in and post it as so. "It's All Good!"

double_click___right_click_in_a_list.au3

Only tested on Windows XP SP2... If your system is different please post is it works or not.

Looks good :)

How come the doubleclick function is being called in the loop instead of in WM_Notify function after If $wParam = $ListViewID And $code = -3 Then ?

Is it just preference or are you trying to prevent an error or speed things up?

A decision is a powerful thing

I still use Win98 and it worked perfect for me. Thanks for sharing! :)

This is the correct way, because if you call a function inside a WM_NOTIFY func (wich is registered func), then you mith expirience some problems...

From the help file:

Warning: blocking of running user functions which executes window messages with commands such as "Msgbox()" can lead to unexpected behavior, the return to the system should be as fast as possible !!!

P.S

Good example gesller, and BTW, there is a diferents between a List Box and ListView :)

WOW!!!! I never knew that!! Thank you for the explanation. I need to get busy on correcting this in my scripts and notify Eltorro in regards to his LV_EditInPlace

Thanks Gesller for the good example and the start of a powerful learning experience.

MSCreator, let me get this straight. I shouldn't call functions in Registered "functions" (eg. WM_Notify) or is this just an issue if the function called takes any "extended" period of time (eg. MsgBox() ) ?

Yes, if you pause the registered function (not return), then when user will execute some option that causing this event (a func) to be called again, you might get some stucks, or even hangs of your script :)

Hello mate:) Since you did the "Right-click function", Got any idea on how to when you click Delete that it removes the thing you selected from the list?:) Would be grateful for it

PS: Using GuiCtrlCreateList instead of GuiCtrlCreateListView:)

Never argue with an idiot, he will just bring you down to his own level and beat you with experience! :D

Sure.. Use this

_GUICtrlListView_DeleteAllItems(GUICtrlGetHandle($Listview1))

Hello.....

I use this to remove a single item from the list.

Func delete()
    Local $ret = MsgBox(48 + 1, "You Right Clicked ", "Delete: " & GUICtrlRead(GUICtrlRead($ListViewID)) & " ?", 10)
    ;# Remove a single item from the list
    If $ret = 1 Then GUICtrlDelete(GUICtrlRead($ListViewID))
EndFunc   ;==>deleteoÝ÷ ÚÚºÚ"µÍ[È[]J
