Hi all, happy New Year.

I am having trouble with some behavior in ContainerNodes that seems a bit odd.

If you take the Anchors.zip official example project (the forum prevents me from providing a link, but if you Google "mindfusion anchors sample" it should be the first result).

And you delete all the code in the Form1_Load() function and replace it with this:

private void Form1_Load(object sender, EventArgs e)
{
            var container = new ContainerNode();
            container.Font = new Font("Segoe UI", 10);
            container.Caption = "テスト";
            container.Bounds = new RectangleF(0, 0, 20, 20);
            diagram.Nodes.Add(container);
}
 

This looks fine when you run it (see attachment: 1.png). Even though "Segoe UI" font doesn't support Japanese characters, the renderer apparently falls back to some other font and displays the text, as is common for WinForms controls.

However if I pass in a Diagram to the ToolContainer constructor, it seems that this breaks the fallback behavior, and the text is rendered as boxes (see attachment: 2.png). That code is like this:

private void Form1_Load(object sender, EventArgs e)
{
            var container = new ContainerNode(new Diagram());
            container.Font = new Font("Segoe UI", 10);
            container.Caption = "テスト";
            container.Bounds = new RectangleF(0, 0, 20, 20);
            diagram.Nodes.Add(container);
}
 

I have to explicitly set a Japanese font, like MS Gothic, instead of Segoe UI, for the text to render correctly (on the 4th line there).

So my question is, how can I give the ToolContainer a parent Diagram while still maintaining font fallback ability?

Thanks in advance.

Thanks Slavcho, happy 2020 to you too.

You are right, I am able to enable font fallback by modifying the TextFormat.FormatFlags like you suggested. It looks like Diagram has TextFormat.FormatFlags == StringFormatFlags.NoFontFallback by default.

For anyone else reading, the solution looks like this:

diagram.TextFormat.FormatFlags &= ~StringFormatFlags.NoFontFallback;
var container = new ContainerNode(diagram);
 

Thanks,
