Thread: Scrollable Label?

Any thoughts?

needScroll is a flag you can set to use if you want too... Labels can be created to scroll, but it would have to be programming in on the plugin side currently...

it's not that hard to get a temp variable and scroll the lables you need to scroll, pulling off the text and invalidating the lable area...

Sorry to be a pain but I am not quite sure how to go about this...

I would need to set some kind of limit based off of the label itself in order to determine when the string I am loading into the label is too long and has to be split.

Which properties could I use to accomplish this?

here you go:

Code:

string text = "new text for the label";
CFControls.skinLabel temp = (CFControls.skinLabel)labelArray[CF_getLabelID("NAMEOFMYLABEL")];

if(text != null)
{
		temp.Text = text;
		temp.Draw = true;
	
		StringFormat sf = StringFormat.GenericDefault; 
		sf.FormatFlags |= StringFormatFlags.MeasureTrailingSpaces;

		Graphics g = this.CreateGraphics();
		int iWidth = (int)g.MeasureString(temp.Text, temp.Font, 0, sf).Width;

		if(iWidth > temp.Bounds.Width)
		{
			//Do What you need to do because the text is too long
		}
		
		g.Dispose();
		labelArray[CF_getLabelID("MAINTITLE")] = temp;
		this.Invalidate(new Rectangle(temp.Bounds.X, temp.Bounds.Y, temp.Bounds.Width, temp.Bounds.Height), false);
}

I put this code into my plug-in and am having issues with the code thinking the text is out of bounds, when it really isn't.

I have attached an example of what I am trying to do.

I am writing a plug-in for AOL Instant Messenger and I need the label to handle two things:

1. Once the message text becomes to large, automatically scroll the label to show the most current text.

2. Via the up and down buttons, allow the user to scroll the text in the label and read older text not currently displayed on the screen.


Hopefully that is descriptive enough, I have tried to work with the example code, but haven't been able to get things working right.

It's as simple as storing the main string in a variable and only updating the labels text with what can fit...

Yes, I guess what I was getting at in the last post was the code you posted was telling me the the main string would be out of bounds when in fact it had plenty of room to fit.

I was wondering if the code you provided was for another use ... say for the main song title label scroll.

It was, you just asked for an example of how to measure a string I thought... It was just an example, not code to copy/paste and use...

sorry for the misunderstanding...

I can help you write what you need after I get RC4 released...

David, any chance that you could help me out with this, this weekend?
