Currently the fltk2 theme stuff is pretty ugly. It's basically a
callback function that fltk calls before opening the window. You then
change a bunch of static stuff kind of directly. The new Style class
does have accessors now, so you should use them instead.
Some very important widgets do not have named styles, like Group, which
is a royal pain, as set_background() is not often what you want.
Here's a (snipped) sample which should be self explanatory I hope - it
changes colors, text sizes and some edge styles on a slider and the
default widget type colors
// fltk group named style bug
extern fltk::NamedStyle* group_style;
bool my_theme()
{
// Reset to fltk's default theme
fltk::reset_theme();
// Change some widget's defaults
int bgcolor = 0x43434300;
int textcolor = 0xababab00;
int selectioncolor = 0x97a8a800;
style = fltk::Style::find( "Slider" );
if ( style )
{
style->color( bgcolor );
style->textcolor( textcolor );
style->buttoncolor( bgcolor );
style->textsize( 8 );
style->labelsize( 10 );
style->labelcolor( textcolor );
style->highlight_textcolor( 0xFFFF0000 );
}
// this is broken...
// style = fltk::Style::find( "Group" );
style = group_style;
if ( style )
{
style->color( bgcolor );
style->textcolor( textcolor );
style->buttoncolor( bgcolor );
style->textsize( 10 );
style->labelsize( 10 );
style->labelcolor( textcolor );
}
style = fltk::Style::find( "Widget" );
if ( style )
{
style->color( bgcolor );
style->textcolor( textcolor );
style->buttoncolor( bgcolor );
style->textsize( 14 );
style->labelsize( 14 );
style->labelcolor( textcolor );
style->selection_color( selectioncolor );
}
// change down box to draw a tad darker than default
fltk::FrameBox* box;
box = (fltk::FrameBox*) fltk::Symbol::find( "down_" );
if ( box ) box->data( "2HHOOAA" );
return true;
}
int main()
{
fltk::theme( &my_theme );
// create widgets normally.
// Any widget with default settings gets the defaults we
// just set.
}
