B4J Question How to send Colors through subs?

[Midimaster]

I would like to send a Jfx-Color to a sub where I asign it to a View, but it looks like the type COLORS in not known in the sub. What do I do wrong?

'this works:
MyButton.TextColor=jfx.colors.red

'this not:
SendColor(jfx.colors.red)

Sub SendColor(Color as Colors)
    MyButton.TextColor=Color
End Sub

jfx.Colors.Red return an INT-Value and MyButton.TextColor needs an Int-Value.

Sub SendColor(Color as Int)
    MyButton.TextColor=Color
End Sub

PS: Sure this is an Android question?

I already tried also this, but it ends up with a crash

Log("Spurrow reset color " & index )
SetTextColor(index,Jfx.Colors.yellow)


Sub SetTextColor(index As Int, Color As Int   )
    StudioSpurItem.TextColor=Color
End Sub

Spurrow reset color 0

It is working for me!
The problem is probably in your definition of StudioSpurItem.Textcolor which should be INT

 

[klaus]

Are you asking for B4A or B4J?
jFX.Colors.Yellow is for B4J and is a Paint object!

In B4A, this works.
SetTextColor(index, Colors.Yellow)

Suggestion: use B4XViews, it will make your life easier.
xui colors are integers for all three platforms.

 

[Midimaster]

oh ! sorry I posted it in B4A. but I need it for B4J

xui colors are integers for all three platforms.

Ah, did'nt know that way! Now it works:

        SetTextColor(1,xui.Color_Red)

As I transscripe my B4A-project to B4J I was happy only need to add a jfx. in front of all my color commands. But now I see it was the wrong way.
