how to add variable/parametr to ListView

Verssuss · May 29, 2017

Hello. The case is complicated as if otherwise ... I'm going to add a parameter or an independent variable (assigned forever to the given item (not to the index)) I have some ideas but everything goes down when an item is drag & drop ...

All what i want is add variable/param to choosen item and move it by any possible way with variable/param added before...
I always move Item but it lost variable/param ;/

here is 2 way i try

Use the Z key to set parameter 11111 on the current item

With the X key we read the parameters from all the items

As I said when indexes 0,1,2 set this parameter, the reading is correct ... while the item is moved to another position, it simply loses part of the information ...

This does not have to be a parameter. Any method is acceptable if it was not visible in the ListView, and the added value persisted after moving the item to another location. First example need Malba23's UDF GUIListViewEx.au3

Please help !!!

Verssuss,

When using native-created ListViews, AutoIt uses the item parameter to store the ControlID of the row - so playing with this value is not a good idea. If you want to associate a value with a certain entry, I suggest you create a hidden (or zero-width) column to store this additional data - I have found that to be a very good method in the past.

sure i already tested that and its low skilled option even each single action on yours 'hidden' box gonna shows again
and ANYWAY i have to do to many column for that coz i need lot of variables. or u show they way to do it on strings ( like separate it ) to keep it in just one column

im sure also there is a way to do it right.

im not that pro to get fun at 3D variables or something but im sure its possible

@Melba23

There are none so deaf as he that will not hear

Verssuss · May 29, 2017

so there is the way to permanent hide any column ? even i have 5 of this ?

show me plz the right way then

mikell · May 30, 2017

Nothing more than what Melba already said
Create the column and set it permanently to zero-width using _GUICtrlListView_SetColumnWidth

Verssuss · May 30, 2017

well. i try my best and now i have example what make it impossible to do...
lets see we have 1000 rows already... and i insert specyfic item on 5 row...
if we want get back right parametr we have to change all params form 5 to end of the list lol

sorry i just realized that...

i still know its possible but it will take to long to change all items into right way

tell me im right xD

i have to stay in hidden columns but i will ask about it latter
PEACE
