When listview loses focus,the selected item,How to keep blue

[kklee69]

When LISTVIEW loses focus,the selected item will turn gray.

How can I change It . Let it continue to stay blue

Do not gray

Never could figure out a clean way to do this, so used the following hack:

Thank you for your reply

It's still turn grayed When I Click on Input BOX

 

[BrewManNH]

Listviews, by design, work this way. The only way you could possibly get this to work is with an owner drawn listview. The standard listview can't work like this.

 

[Subz]

Sorry you need to remove $LVS_SHOWSELALWAYS i.e.

$listview = GUICtrlCreateListView("NO1  |NO2|NO3  ", 10, 10, 200, 150, $LVS_SINGLESEL , $LVS_EX_FULLROWSELECT)

OK!!  it works very well

But it doesn't Work in multi-selection mode

After losing focus, only one item Keep blue

I still want to thank you for providing such good code

This can be done by drawing selected back and fore colors with GDI functions in custom draw post paint stage:

I have asked questions in your Virtual ListViews forum !!
I don’t know if you have time to help me

[JLogan3o13]

@kklee69 in the future please just hit reply rather than quoting every single response. We know what we said (we were there when we said it), and it pads the thread unnecessarily.

Ok, I understand
I am Chinese
Not used to the English version of the website
I will pay attention next time

Just wanted to add Multi-Selection mode method using my method above, I had to use it this week in a script so thought I'd share the code.

Hi,

I'm working on the same thing.

In the example, is it possible to turn off the highlighted row using the button rather than going through WM_NOTIFY

I went another direction.  Thanks.
