You show a video that looks like it is working, the title of your threead says: not fully working, but the project crashes with following error. So what is the verdict.

but it works-not lying.. wait a little i will upload an update with some new features..

Magma · Mar 24, 2022

updated...

Added double click to restore width - hide column (width:1 dip)
Added Timer to check scrollbar x (so... now you can move the scrollbar too)

...I think now it is someway ready... if someone want to to work with the order of columns be my guest... also... if someone find the way to calculate searchbox, buttons height or scrollbar height (is easy i think).. .tell me to fix it...

Sorry. Even with your new version I have the same problem. It has nothing to do with what you mentioned as the reason in post#5. Maybe someone can report to you if it worked for them, then I do not know what my problem is. Maybe someone else can tell us. ANyway, thank you, I do not have to have that feature, as I do not need it. I just wanted to help by testing it.

Very strange...
I would like to listen other members too..

Today I am not in office/on PC ... to check the zip again..

Or screenshot libs using.. I am not remember anything special... is just the example of b4xtable erel made old days

+testing done with Release only if that helps...

Ps: as I am reading your post (Mahares, I understand that you using debug mode.. As I remember I was testing in Release mode)

It runs in release, but crashes in debug. Now, I can check it out. I am surprised no one that tested it did not bring it up to our attention earlier.

I have eliminate the error by removing the casting:

B4X:

hheaderpanel = xui.CreatePanel("hhheaderpanel")

Mahares said:
It runs in release, but crashes in debug.

The crash in debug happened in hhheaderpanel_MouseExited when the Sender is null and I may have fixed/bypassed it with the following:

B4X:

Private Sub hhheaderpanel_MouseExited (EventData As MouseEvent)
    If EventData.PrimaryButtondown Then Return
    Dim pane1 As B4XView = Sender
    ' modified by aeric
    Log(Sender)
    'pane1.SetColorAndBorder(xui.Color_Transparent, 2,0,0)
    If pane1.IsInitialized Then
        pane1.SetColorAndBorder(xui.Color_Transparent, 2, 0, 0)
    End If
End Sub

And I am not sure the following help but I think no harm to add it inside Sub Class_Globals:

B4X:

#RaisesSynchronousEvents: hhheaderpanel

P/S: I thought to change the mouse cursor using

B4X:

pane1.As(Pane).MouseCursor = fx.Cursors.H_RESIZE

but H_RESIZE does not exist.

Magma · Mar 29, 2022

when you say... removing the cast... ? how did you add the pane... as simple pane ?

a code... or a zip will be helpful for all...

did anyone tried at b4a or thought a way to use there ?

aeric · Mar 29, 2022

Magma said:

You already define the variable hheaderpanel As B4XView in Class_Globals on top:

B4X:

'added by MAGMA:
Dim hheaderpanel As B4XView

So you do not require to cast it again as B4XView.

B4X:

' modified by aeric
'hheaderpanel.As(B4XView) = xui.CreatePanel("hhheaderpanel")
hheaderpanel = xui.CreatePanel("hhheaderpanel")

Magma · Mar 29, 2022

now I am seeing.. ~~but the crash error in debug mode... in any event sub hheadpanel_ ... :-( and not bypassed / fixed~~

yes Works ! - great work aeric
