5 posts in this topic

#1 ·  Posted (edited)

Hey, in my program i would like the user to be able to edit the text in a list view item, by right clicking and pressing edit. I made a context menu for the list view so when i right click it, the edit option comes up, but i just need to figure out how to be able to change something inside like i would a excel cell. Incase im not clear ill take a screenshot of what i want my program to be able to do:

I'm guessing this will be for your own AutoIt script:

#include <GuiConstants.au3>
#include <GuiListview.au3>

Global Const $DebugIt = 1

Global Const $WM_NOTIFY = 0x004E

Global Const $NM_FIRST = 0
Global Const $NM_CLICK = ($NM_FIRST - 2)
Global Const $NM_DBLCLK = ($NM_FIRST - 3)

Global $ListView = -999
Global $Gui, $editFlag
Global $editCtrl = "Edit1";name of the Edit control that pops up when edit a listitem....

Is there a way of editing specific data for a listviewitem without using "|"? Just double click on some data and modify it?

Did you try the above post?

The above will only work on the 1st column.

If you need to work on other columns, might check with Holger.

Yes I modified the code to have two columns and if you double click on a listview item on Column #2. The entire row is editable and you have to use "|" to change the data. Bascially how excel works. Just double click on a cell and you can edit just that cell instead of having to use the "|". For some reason when I quit out of the code the "scroll up" key was stuck.
