Limit width of TitledPane in a ScrollBox

Question

Hi
This is probably a beginnersquestion but i wasn't able to solve that by myself (and the Help of Google).
I have several TitledPanes in a VBox in a ScrollPane. The ScrollBox should only scroll in vertical direction. If the TitledPanes have a title which is longer than the width they increase the width of the ScrollPane/VBox. How can i limit the width of these so that no horizontal scrolling is possible?
Thanks
Fabian

Leaving aside the fact that one of my program always has Font as
"ControlFont" on the 1st call of GetCtrlAttribute/ATTR_TEXT_FONT,
consider the complete code below. Why does the value of font changes ?
When I create a meta font, I'm not asking it to assign it to some control!
#include <userint.h>
int main (int argc, char *argv[]) {
char font[255]="", Typeface[255];
int fontSize, bold, italics, underline, strikeout;
char Str[]="Some long string of text";
int Pnl, Ctrl, TextWidth=0, r;
Pnl = NewPanel (0, "Test", 20, 20, 200, 200);
Ctrl = NewCtrl (Pnl, CTRL_RING_LS, "Test", 0, 0);
InsertListItem (Pnl, Ctrl, -1, Str, 0);
GetCtrlAttribute (Pnl, Ctrl, ATTR_TEXT_POINT_SIZE, &fontSize);
GetCtrlAttribute (Pnl, Ctrl, ATTR_TEXT_BOLD, &bold);
GetCtrlAttribute (Pnl, Ctrl, ATTR_TEXT_ITALIC, &italics);
GetCtrlAttribute (Pnl, Ctrl, ATTR_TEXT_UNDERLINE, &underline);
GetCtrlAttribute (Pnl, Ctrl, ATTR_TEXT_STRIKEOUT, &strikeout);
GetFontTypefaceName (font, Typeface);
GetCtrlAttribute (Pnl, Ctrl, ATTR_TEXT_FONT, font);
r=CreateMetaFont ("Something", font, fontSize, bold, italics,
underline, strikeout);
r=GetTextDisplaySize(Str, "Something", 0, &TextWidth);
// font is now NIDialogMetaFont
GetCtrlAttribute (Pnl, Ctrl, ATTR_TEXT_FONT, font);
r=CreateMetaFont ("SomethingElse", font, fontSize, bold,
italics, underline, strikeout);
r=GetTextDisplaySize(Str, "SomethingElse", 0, &TextWidth);
// font is now Something
GetCtrlAttribute (Pnl, Ctrl, ATTR_TEXT_FONT, font);
r=CreateMetaFont ("YetAnotherThing", font, fontSize, bold,
italics, underline, strikeout);
r=GetTextDisplaySize(Str, "YetAnotherThing", 0, &TextWidth);
// font is now SomethingElse
return 0;
