splitting a long string into multiple strings

That's a good plan. Then all you should need to do once the library is released is add a reference to the assembly, and then get rid of the widget source code from your project.

ok i got the scrolling text box working, i did have to modify the code a little, with the methods available in gbpvr concerning skinning, its not really easy to get a font colour, you can easily get a font brush however (from composite images i mean), so i had to add a property to get/set the fontbrush, and use that brush in the drawstring method. but other than that, its working great, thanks jasonf.

True, the abstract Brush class does not have a color property, but a SolidBrush does:

(brush as SolidBrush).Color

Just FYI (since there's no documentation yet): Another thing that you could have done is used the SetElement(string) method to set different style properties individually, or Apply(string) to set multiple style properties all at once.  The expected string adheres more-so to HTML/CSS than to the corresponding properties of the controls and/or Style.  This is all part of the work that I'm trying to wrap up on the framework-side of the library.

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">
       scrollingTextbox.Style.Apply("color:white; border-color:black; border-style:rounded; border-radius: 10;");
       scrollingTextbox.Style.SetElement("font:Arial,14,bold italic");

Quote[/b] ](brush as SolidBrush).Color

ok, yeah i thought it was weird that brush didnt define colour.

whats the memory management like on this, i didnt really look at the code all that much, just wondering if you dispose the images etc in the .Text set property, im using the same textbox, just with different text for a lot of things (well every single movie, just changing the text), also using it for every single actor (ie just 2 different textboxes).

[jasonf]

The image is not cached--it's created during the Render() method, drawn to the graphics object, and then disposed.

Oh, and you probably saw this, but there's a OnKeyDown() method that you can pass the KeyEventArg to from the plugin to handle scrolling when the textbox has focus. In addition, you can &quot;manually&quot; control scrolling using the CursorUp(), CursorDown(), CursorLeft(), and CursorRight() methods.

[reven]

yeah the cursorup/down was to slow, i just manually increment it by 10 pixels when the user pushes page up/down, its not as smooth, but a much quicker.

i just usedthis
<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">/// <summary>
/// Gets or sets the current vertical scroll position, in pixels, of the full rendered string.
/// </summary>
public int CurrentScrollY
{
get { return currentScrollY; }
set { currentScrollY = value; }
}[/QUOTE]
i changed it to this, just as a safety test (you might have already taken care of this, but i didnt want it to crash, or produce weird results
<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">/// <summary>
/// Gets or sets the current vertical scroll position, in pixels, of the full rendered string.
/// </summary>
public int CurrentScrollY
{
get { return currentScrollY; }
set { currentScrollY = value;
if(currentScrollY <0)
currentScrollY = 0;
}
}[/QUOTE]

[jasonf]

Did you see the ScrollPercentage property? That's where you adjust the &quot;jump&quot;.

By default, it scrolls 1% of the window size. You can set it to any value from 1-100, with 100 meaning that each scroll will jump the height/width of the window (depending on the scrolldirection).

Where did you manually change it to 10 pixels?

[reven]

textBox.CurrentScrollY += 10;
textBox.CurrentScrollY -= 10;

[jasonf]

Ah. You can do that, but the better way would be to use CursorUp() and CursorDown(). If the jump is too small, set the ScrollPercentage to maybe 33 (so each scroll will be 1/3 of the control height).

And you would be right to put safety code in the CurrentScrollY property--that's something that I'll need to add.
