Dear JGO,
I'm currently writing a game with Slick2D and NiftyGUI (v. 1.3.2). As always I've created a simple XML file with a center aligned panel. The panel contains two labels (horizontal oriented):

1  
2  
3  
4  
5  
6  
7  
8  
9  
10  
11  
12

>
<useStyles filename="nifty-default-styles.xml" />
<useControls filename="nifty-default-controls.xml" />
<screen id="start">
   <layer>
         <!-- Caption -->
         <panel childLayout="horizontal" align="center">
            <control
               id="lblCaption"
               name="label"
               color="#bccf39"
               text="caption"
            />
            <control
               id="lblVersion"
               name="label"
               text="version"
               marginLeft="10px"
               color="#ff6000"
            />
      </panel>
    </label>
</screen>

I can change the text content of those controls in Java:

1  
2  
3  
4  
// Inside a screen controller...
Label lblVersion = screen.findNiftyControl("lblVersion", Label.class);
Label lblCaption = screen.findNiftyControl("lblCaption", Label.class);
lblCaption.setText("A very long long long long long text!");

The text will be changed - but not the width of the label! The result: the text is cropped. That's very annoying. I've tried the following solution to solve the problem:

1  
2  
3  
4  
TextRenderer renderer = lblCaption.getElement().getRenderer(TextRenderer.class);
lblCaption.setWidth(new SizeValue(renderer.getTextWidth() + "px"));
// Update the panel and all children
lblCaption.getElement().getParent().getParent().layoutElements();

This works for me but it's not a very elegant way. Has anyone experience with this problem?  Huh

Add your game by posting it in the WIP section,
or publish it in Showcase.
