B4J Question Get / Set ColorPicker Color (String/Int)

[Mashiane]

Hi

I want to get and set the color of a ColorPicker using my crud db app. The color picker returns a Paint object. How do I get the returned color as a string/int and also be able to set it when I read the saved color from a db?

This post so far I have been able to get the RBG, perfect! Now setting the color is the issue. Any help please.

You can convert a color to int with fx.Colors.To32Bit.

Later you can convert it to a paint with fx.Colors.From32bit.

What is fx, please?

FX is a module that comes with ui projects. Look for it on global variables in main. If it is not there then you are not in a ui app

And this thread is old, if you are in a ui app then it's better to use xui

How to convert Color to int using xui? Please give an example.

I've already looked for B4A-XUi. I can't find it. Can You write an example?

 

[EnriqueGonzalez]

    Dim p As Paint = fx.Colors.Black
    Dim i As Int = xui.PaintOrColorToColor(p)
    Log(i)

 

[goomoo]

    Dim p As Paint = fx.Colors.Black
    Dim i As Int = xui.PaintOrColorToColor(p)
    Log(i)

Which brings me back to my previous question, where did this FX come from?

 

[EnriqueGonzalez]

Sub Process_Globals
    Private fx As JFX

if you can't find it there, then you are not using an UI project

OK!
