Hi there

On a layout I have a HexMenu + WoobleMenu, the HandleResizeEvent is on. This ensures that everything else resizes itself and shows up. Good.

Individually these components work well, however as soon as I add a wobble menu to a page, the hexmenu crashes.

B4X:
Private Sub Base_Resize (Width As Double, Height As Double)
    Dim mn As Double = Min(Width, Height)
    iv.SetLayoutAnimated(0, Width / 2 - mn / 2, Height / 2 - mn / 2, mn, mn)
    pnl.SetLayoutAnimated(0, iv.Left, iv.Top, iv.Width, iv.Height)
    bc.Initialize(iv.Width, iv.Height)
    bc.FillGradient(Array As Int(0xFFFF000E, 0xFFFFF0A1), bc.TargetRect, "TL_BR")
    GradientBrush = bc.CreateBrushFromBitmap(bc.Bitmap)
    Update
End Sub

On this line:
GradientBrush = bc.CreateBrushFromBitmap(bc.Bitmap)

This is the error

B4X:
Error occurred on line: 101 (HexMenu)

)


When HandleResizeEvent if off, no crash happens, however the WobbleMenu does not show at the bottom and the hex is placed further down the page.

Please help.

Thanks.[/code]
 
Solution
I have a fix.
@Erel you need to limit the width and height, if the width or height = 0 then this error happend
Fix:
B4X:
bc.Initialize(Max(1dip,iv.Width),Max(1dip, iv.Height))
Line 93 in the HexMenu.

can you reproduce it in an example project?

Thanks, please find attached small project. Here is also a video recording as POE.


PS: Please note that this happens in a similar fashion when the layout is also loaded in the B4XMainPage.

For anyone who might experience the same issues on IOS, please find the updated HexMenu.

1. In the property bag I have added a Multi-Line property - use this if you want to use CRLF on the text that you will insert in the items
2. In the property bag I have added UseCSBuilder property - use this if you want to use CSBuilder on the items creations.
3. Updated the code as above to make the Hex & Wobble Menu to play well together.

1 & 2 - Help credit to Erel
3 - Help credit to Alexander

PS: This hex menu was just updated to meet my IOS needs. Things are different with IOS.

Many thanks to Erel and Alexander.
