Listview Add Buttons problem?

Post by scriptor2016 » 23 Jan 2022, 04:55

Greetings to all on this fine late night

So I've come across this problem. With the script immediately below, the listview scrolls endlessly if you click on the empty space below or above the scrollbar. So for example, try the following:

-Run the script
-Don't press any buttons or do anything- just proceed to the step below:
-Hover the cursor just above the 'down' arrow in the scrollbar column on the right side of the gui
-left-click once
-the scrollbar will continuously scroll downwards until it hits the bottom
-and then if you immediately click just below the 'up' arrow, the scrollbar will scroll repeatedly upwards until it hits the top... and so on

..the problem is, it should only scroll down one time. But it is scrolling down repeatedly until it gets to the bottom or top of the listview for some reason.

Here's the code:

Code: Select all


Gui, Add, Button, x0 y0 w70 h21, BUTTON1
Gui, Add, Button, x75 y0 w70 h21, BUTTON2

return

{
    LV_GetText(RowText, A_EventInfo)  ; Get the text from the row's first field.
    ToolTip You double-clicked row number %A_EventInfo%. Text: "%RowText%"
}
return



GuiClose:  
ExitApp


ButtonBUTTON1:
msgbox, BUTTON1
Return

ButtonBUTTON2:
msgbox, BUTTON2
Return

ButtonBUTTON3:
msgbox, BUTTON3
Return




However... if I alter the code and move the "Gui, Add, Button" lines down to underneath the "LV_Add" portions, then this problem stops. Here's the updated code for that:

Just for argument's sake, why is the placement of adding the buttons in the code causing the scrolling problem?

Hmm. Strange. I even closed all other scripts and I'm still getting this problem.

I'm on Win7 64 bit. I'm wondering if that might be an issue.

Man, this is odd. The top script posted above causes a problem on my end, but the bottom script acts normally.

If I run the top script, this is the sequence that causes the problem:

-Run the script
-Hover the cursor into an empty space in scrollbar column - and now the 'up' and 'down' arrows should become visually highlighted/activated (they become darker)
-Left click once, and the scrollbar repeatedly scrolls towards the cursor placement. (Try and click well above or below the scrollbar's current position so it has space to scroll repeatedly)
-Now, the 'up' and 'down' arrows have become de-highlighted
-So again, we must click on an empty space in the scrollbar column, so that the 'up' and 'down' arrows are once again highlighted/active(darker in color)
-Click again in the same spot, and the scrollbar will repeatedly scroll again

Sorry I can't explain this better lol. Hopefully someone will run across this same issue. The bottom script works, however. Just by changing the placement of adding the buttons. It's for sure an issue with adding the buttons, because if I remove the buttons altogether then this problem disappears. Sorry I don't have video capabilities to demonstrate.

no worries haha.

But this is an issue I really can't figure out... maybe someone with Win7 might be able to chime in at some point. Cheers :D
