Change icon of checked/unchecked checkbox, and sort them correctly.

[MrCreatoR]

Hi all,

In next example, i had to use some code that i has found somewhere here on the forum (please except my apologies the author of this script, i really can not find it).

This example is show how you can change the icons during the checking certain checkbox. I mean, if you check one checkbox, and even if you not select the item itself, the icon of that item is changed, if you uncheck it, then the icon is changing back...

So my problem is, when i starting to sort the items (if some of them have different icons and check states), then i see one big confusion of the items, and they icons when i trying to check/uncheck them again.

If someone could tell me, how to fix this problem, or even it's be better, if there is a way to get the text of the checked/uncheck item (and even if this item is not selected), it will be great - i am will be very grateful.

Here the example:

hi,

Here's a nearly working workaround (* needs many of the files in mu GUIListView zip from signature to work)

At present, click on column 1st time only 3 times! oh well, gives the idea;

Wow! thanks, it works.

Maybe you also know, how to get "check state" event? i mean, if i check/uncheck the checkbox of listvivew item, and the item is not selected, then i would like to see a MsgBox with a text of that item... but without actualy over the all items to see if they checked or not (as i did in my example), just for one item. It is possible?
