Need help setting foreground color

[jdhitsolutions]

I'm not sure what I'm doing wrong, or perhaps I'm misunderstanding the documentation. I'm doing this in PowerShell in PowerShell 7 and it mostly works. I can define a textview in a frame like this.

$txtDetail = [TextView]::New()
$txtDetail.Text = 'Process Details'
$txtDetail.ReadOnly = $True
$txtDetail.x = 1
$txtDetail.Width = [Dim]::Fill()
$txtDetail.Height = [Dim]::Fill()

$n = [Terminal.Gui.Attribute]::new("BrightGreen","magenta")
$cs = [Terminal.Gui.ColorScheme]::new()
$cs.focus = $n
$TxtDetail.ColorScheme = $cs
$Frame2.Add($txtDetail)

I can get the background in the right-hand frame to change.

Is there something I'm missing to get the foreground color applied? Or how would you do it from C#?

As far as I can tell, the color scheme is properly defined.

Value          : 90
Foreground     : BrightGreen
Background     : Magenta
Initialized    : True
HasValidColors : True

But it doesn't render. I'm running this in Windows Terminal.

The ColorScheme class has various Attributes (Normal, Focus, HotNormal, HotFocus, Disabled). You only defined the Focus attribute and the others aren't valid.

[jdhitsolutions]

So I set all attributes to use the same color scheme? I don't think I'm completely understanding the different attributes.

ColorScheme isn't a unique color attribute setting. As I said it has a set of attributes for when haven't focus (Normal), when have focus (Focus) etc. I see the TextView has not the focus and perhaps is using the magenta and white color (default). Set at least the Normal attribute.

Hi @jdhitsolutions thanks reaching out. ColorScheme defines the colors (Attribute) which should be used in each of the given states a View can be in. But if you are setting them all to the same attribute then it should just work.

Here is the C# that results in something similar to your screenshot. Hopefully it will give you some insight into your problem.

using System.Text;
using Terminal.Gui;

Application.Init();

var w = new Window();
var left = new FrameView() { Width = Dim.Percent(50),Height = Dim.Fill(), Title = "Process List" };
var right = new FrameView() { Width = Dim.Percent(50), Height = Dim.Fill(), Title = "Process Details", X = Pos.Right(left) };

var allGreen = new ColorScheme
{
    Normal = new Terminal.Gui.Attribute(Color.BrightGreen, Color.Magenta),
    Disabled = new Terminal.Gui.Attribute(Color.BrightGreen, Color.Magenta),
    Focus = new Terminal.Gui.Attribute(Color.BrightGreen, Color.Magenta),
    HotFocus = new Terminal.Gui.Attribute(Color.BrightGreen, Color.Magenta),
    HotNormal = new Terminal.Gui.Attribute(Color.BrightGreen, Color.Magenta),
};

var txtDetail = new TextView()
{
    Text = @"This is a test of the emergency
broadcast system.
Zombies are approaching, flee fast!",
    ColorScheme = allGreen,
    Width = Dim.Fill(),
    Height = Dim.Fill(),
    ReadOnly = true
};

right.Add(txtDetail);

var listView = new ListView(new List<string> { "Cat", "Dog", "conhost" })
{
    Width = Dim.Fill(),
    Height = Dim.Fill(),
};

left.Add(listView);

w.Add(left);
w.Add(right);

Application.Run(w);
Application.Shutdown();

I found that if I set the Focus and Disabled attributes to my color scheme, I get the desired result. Not intuitive, but I'm used to hacking my way to the end. Thanks for the comments.

You welcome. I think set the Focus and the Normal you would got the same result. That the way how ColorScheme works which is more complex than only set only one foreground and background.
