Different "style" for one specific control

Mar 30, 2011 at 6:51 PM

I was wondering about changing skins for one or more controls. I noticed the whole skinning routine is somewhat similar to CSS, can I make somehow a different "style" for specific control(giving an "id" to one labelcontrol).

I've just started to port my WIP game to Nuclex (mainly for GUI support) and needed this too, so here's how I did it for LabelControl (I'll change the code for each control when I need it):

1. Added the CustomFrame field to LabelControl to allow specifying a frame only for one instance (a label, in this case):

  /// <summary>Control that draws a block of text</summary>
  public class LabelControl : Control {
      /// <summary>If this is non-null, the custom frame will be used for rendering</summary>
      public string CustomFrame;

2. Changed the renderer to use that field, if it exists:

  /// <summary>Renders label controls in a traditional flat style</summary>
  public class FlatLabelControlRenderer :
    IFlatControlRenderer<Controls.LabelControl> {

    public void Render(
      Controls.LabelControl control, IFlatGuiGraphics graphics
    ) {
        if ((null != control.CustomFrame) && (control.CustomFrame.Length > 0))
        {
            graphics.DrawString(control.CustomFrame, control.GetAbsoluteBounds(), control.Text);
        }
        else
        {
            graphics.DrawString("label", control.GetAbsoluteBounds(), control.Text);
        }
    }

3. Add a new frame to the skin XML file:

    <frame name="mgtitle">
      <text font="funnybig" hplacement="left" vplacement="center" yoffset="15" color="#FAD200" />
    </frame>

4. Set your custom frame:

            LabelControl title = new LabelControl("Title");
            title.Bounds = new UniRectangle(new UniScalar(0f, 300f), new UniScalar(0f, 50f), 200, 50);
            title.CustomFrame = "mgtitle";

And that's it. Few new lines of code :)

Don't know how easy is to do the same for each control, I'm just starting to know Nuclex but you can develop from here.
