I'm getting the following exception when changing my application font, because I use a strike out in a part of my application, and some fonts don't support it:
I change my application font using a font dialog. I need to check if the selected font supports the strikeout style after assigning it to my application.
What is the recommended way to do this? I know I could create a font with the style and catch the exception, but is there a more elegant way to do it?
Thanks in advance.
EDIT: The user selects a font, not necesary strikeout. In that moment I need to check if the font supports the style strikeout, because I create a strikeout font in a part of my application. If the font don't support the strikeout style w开发者_Go百科ould not allow the user to choose that font.
Updated : (to reflect update in the initial post):
InstalledFontCollection ifc = new InstalledFontCollection();
for (int i = 0; i < ifc.Families.Length; i++)
{
if (ifc.Families[i].IsStyleAvailable(FontStyle.StrikeOut))
{
//add particular font with this family to your "font selector"
}
}
If you are using the standard Font
class, then you can use the Font.Strikeout property:
//Gets a value that indicates whether this Font specifies a horizontal line through the font.
public bool Strikeout { get; }
Finally I used the following:
private bool SupportStrikeout(Font font)
{
try
{
using (Font strikeout = new Font(font, FontStyle.Strikeout))
{
return true;
}
}
catch (ArgumentException)
{
return false;
}
}
