Detect ListView Item delay click

[Trolleule]

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!

[AutoBert]

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.
