Re: font size gtk_*_new_with_label [SOLVED]

[Luis Ariel Lecca <ariel_xxii yahoo com ar>]

thanks to the 3 guys who gave me a hand with this...

Here one function in C to resolve this:

gint8	GuiUtils_Font_Change( GtkWidget *pCtrl, c8 *C8pname, PangoFontDescription *pfont )
{	
	gint8	S8retval = -1;
	
  if( C8pname && pfont )
	{	
		if( GTK_IS_WINDOW(pCtrl)/*||GTK_IS_LIST_ITEM(pCtrl)*/ )
		{	
			pCtrl = lookup_widget( pCtrl/*GTK_WIDGET(pCtrl)*/, C8pname );
		}	
		
		if( pCtrl )
		{	
			if( !GTK_IS_LABEL(pCtrl) )
			{	
				if( GTK_IS_BUTTON(pCtrl)||GTK_IS_ITEM(pCtrl) )
				{	
					pCtrl = gtk_bin_get_child( GTK_BIN(pCtrl) );
				}	
				else if( GTK_IS_STATUSBAR(pCtrl) )
				{	
					pCtrl = GTK_WIDGET((GTK_STATUSBAR(pCtrl)->label) );
				}	
				else if( GTK_IS_FRAME(pCtrl) )
				{	
					pCtrl = GTK_WIDGET((GTK_FRAME(pCtrl)->label_widget) );
				}	
				else if( GTK_IS_ENTRY(pCtrl) )
				{	
					pCtrl = lookup_widget( &((GTK_ENTRY(pCtrl)->widget)), C8pname );
				}	
			}	
			
			if( pCtrl )
			{	
				gtk_widget_modify_font( pCtrl, pfont );
				S8retval = 0;
			}	
		}	
	}	
	
	return S8retval;
}
