First off I'm sorry it took me this long to reply, but I was otherwise preoccupied and the notification mail got lost/spammfiltered or i simply overlooked it. (that and I must admit, I kinda forgot about LVA :oops: ).
Then the problems:
The problem I'm having is that the listview is on a second gui. When you destroy and reopen the Gui, I run into both lagginess and a redrawing problem. Does LVA not handle a destroyed and recreated Listview?
In short: NO. LVA was never intended to handle destruction and recreation of listviews. Everytime a control is created it is assigned a Handle, and this handle is used internally to keep track of which listview is currently redrawing. So everytime it is destroyed the handle changes and thus the previous data is invalid. That might be a reason for the lagginess, but I can't be sure.
To fix freezing bug you can also try this:
1. Remove subclassing. Put return in lva_Subclass function as first line.
2. Put critical 500, in lva_OnNotify function.
Well since I never encountered this freezing bug, I opted to have the subclassing as standard, an apologize to everyone that encountered this.
I'll upload a new version with critical in it, and subclassing standard off.
But the subclassing is noted in the Docs: Set 3rd parameter of LVA_ListViewAdd (UseFix !) to false.
Is it possible that someone could develop a function to draw a line through the cell to create a strike through look?
This is almost already possible, but has nothing to do with this function. What needs changing is the font part of the current cell. As it stands its a minor change to the code to include a check for the font, but I had/still have trouble parsing the font format, since per windows you are only allowed to change a few properties of the font.
So all in all, I'm sorry it took me this long to respond, but I'll upload a minor bugfix version right away. Edit: Uploaded v1.1
If I get around to it in the next 2-3 weeks, I'll rewrite it from scratch (more or less), and try to include better support for listview destruction and font.
