Couple Simple Questions

[FinalVersion]

1. How can I have multiple Styles or ExStyles? I've tried this.

GUICtrlCreateListView("Process Name|Process ID (PID)", 8, 8, 362, 382, ($style1, $style2))

It appears it didn't work.

2. How can I make columns in ListView's automatically adjust to the largest size text in the column?

3. Is it possible for a ListView to update in realtime? And how would I go about it?

FinalVersion,

Having a busy day, aren't we!

multiple Styles or ExStyles

You use BitOR like this:

BitOR($WS_MINIMIZEBOX, $WS_CAPTION, $WS_POPUP, $WS_SYSMENU)

A couple of points:

1. Do not use simple addition - although it might work in some cases, Windows often uses the bits as markers and addition can set bits you do not want - then you take ages working out why you have not got what you think you should have (speaking from personal experience here!)

2. When you ever specify a style setting, you overwrite all the previously set styles. If you wish to retain them you must add them back in as well. A common example: the default styles for a ListBox are $LBS_SORT, $WS_BORDER, $WS_VSCROLL; if the $LBS_NOTIFY style is used on its own when the ListBox is created, it overwrites these and the user wonders why the ListBox no longer sorts and has no scrollbar! You have to BitOR the lot (although there is a shorthand way of defining the default styles for most controls - look in the Help file)

2a. You can retrieve the current style setting via an API call and use BitOR again, but we will leave that for another day....

make columns in ListView's automatically adjust to the largest size text

Use _GUICtrlListView_SetColumnWidth with $LVSCW_AUTOSIZE in the $iWidth parameter. Look in the Help file for more details.

Is it possible for a ListView to update in realtime

No, you have to update the ListViewItems in a loop.

Indeed it is a big day. Can you give me an example of multiple styles & exstyles, thanks.

Hey, look in the help. GuiCreate is one but there are loads.

EDIT: and since you have been told the answer, what on earth prevents you from just tring it? All you have to do is put BitOr around the style you used in your first post.

FinalVersion,

Does Sir want fries with that?

Run this 3 times using the relevant creation line each time:

#include <GUIConstantsEx.au3>
#include <ListboxConstants.au3>

$hGUI = GUICreate("Test", 500, 500)

$hList = GUICtrlCreateList("", 10, 10, 250, 100) ; run this one first
;$hList = GUICtrlCreateList("", 10, 10, 250, 100, $LBS_NOTIFY) ; run this one second
;$hList = GUICtrlCreateList("", 10, 10, 250, 100, BitOR($GUI_SS_DEFAULT_LIST , $LBS_NOTIFY)) ; run this one third

GUICtrlSetData($hList, "1|2|6|4|7|3|5|8|9") ; unsorted list

GUISetState()

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch

WEnd

First run will give you a sorted list with a scroll bar.

Second run will give you an unsorted list and no scroll bar - you have overwritten the default styles by specifying $LBS_NOTIFY.

Third run gives you a sorted list and a scroll bar.

Clear?

I tried this, but it fails.

$lstProcesses = GUICtrlCreateListView("Process Name|Process ID (PID)", 8, 8, 362, 382 BitOR($LBS_SORT, $WS_BORDER, $WS_VSCROLL,$LVS_SINGLESEL, $LVS_SORTASCENDING))

ERROR: GUICtrlCreateListView() [built-in] called with wrong number of args.

I know the error says BitOR has to many parameters. I given it 5, you showed me 4, I believe max is 3. How do I fix this?

[FinalVersion]

Ah didn't see your second post, anyway I tried your 3rd example, and AutoIt thinks $GUI_SS_DEFAULT_LIST and $LBS_NOTIFY are variables.

I got it working with just "$LVS_SORTASCENDING" and without using BitOR, for the moment it appears to do what I want.

up to 255 values can be specified to BitOR

The error is a missing comma between the number 382 and BitOR.
