1. wxEuphoria - Menu Font

I modified Menu-demo.exw program creating new fonts. The new fonts work well in another of the demo programs.

#!/home/matt/euphoria/bin/exu 
-- example8.exw 
-- 
-- This example places a menu in a window 
 
without warning 
 
include wxeu/wxeud.e 
 
object void 
 
global integer 
-- Courier new 9 point 
	euCNNorm9 = create( wxFont, {9,wxDEFAULT,wxNORMAL,wxNORMAL,0,"Courier New"}),   
-- more here Bold, Italics, Underlined etc 
-- Courier new 10 point 
	euCNNorm10 = create( wxFont, {10,wxDEFAULT,wxNORMAL,wxNORMAL,0,"Courier New"}), 
-- more here Bold, Italics, Underlined etc 
-- Times New Roman 9 point 
	euTNRNorm9 = create( wxFont, {9,wxROMAN,wxNORMAL,wxNORMAL,0,"Times New Roman"}), 
-- more here Bold, Italics, Underlined etc 
-- Times New Roman 10 point 
	euTNRNorm10 = create( wxFont, {10,wxROMAN,wxNORMAL,wxNORMAL,0,"Times New Roman"}), 
-- more here Bold, Italics, Underlined etc 
-- Times New Roman 12 point 
	euTNRNorm12 = create( wxFont, {12,wxROMAN,wxNORMAL,wxNORMAL,0,"Times New Roman"}), 
	euTNRItal12 = create( wxFont, {12,wxROMAN,wxITALIC,wxNORMAL,0,"Times New Roman"}), 
-- more here Bold, Underlined etc 
-- Arial 10 point 
	euARNorm10 = create( wxFont, {10,wxDEFAULT,wxNORMAL,wxNORMAL,0,"Arial"}), 
	euARBold10 = create( wxFont, {10,wxDEFAULT,wxNORMAL,wxBOLD,0,"Arial"}), 
$ 
 
constant MenuWin =  
    create( wxFrame,{0,-1, "Menus"} ), 
    win = create( wxPanel, {MenuWin}) 
     
constant 
MenuBar = create( wxMenuBar, {MenuWin}), 
FileMenu = create( wxMenu, {MenuBar,"&File"}), 
    MenuNew     = create( wxMenuItem,{ FileMenu, wxID_NEW,"&New\tCtrl+N"}), 
    MenuOpen    = create( wxMenuItem,{ FileMenu, wxID_OPEN, "&Open"}), 
    MenuSave    = create( wxMenuItem,{ FileMenu, wxID_SAVE, "&Save"}), 
    MenuSaveAs  = create( wxMenuItem,{ FileMenu, wxID_SAVEAS, "Save &As"}) 
	append_separator( FileMenu ) 
-- etc etc 
-- etc etc 

I added :

set_default_font ( win, euARBold10) 
set_default_font (MenuWin, euTNRItal12) 

I put one or both of these lines separately or together in various places to see if the font will change on execution, but the font remains the same. I also tried and failed with using MenuBar instead of win or MenuWin

--   set_default_font (MenuBar, euTNRItal12) 

I also was not able to use later

set_menu_label ( MenuBar, FileMenu, "MyFileMenu") 

I am new to Euphoria and wxEuphoria. I shall appreciate help or direction to a working wxEuphoria program where the Font in the Menu can be changes dynamically, and the text of the labels can also be changed dynamically or redrawn or something like that.

It looks like one can do this in wxWidgets 2.9 (that's all I checked) by simply calling SetFont() on the wxMenuItem object (but not wxMenu or wxMenuBar). If it's that simple then we'd just have to wrap it in the code (set_menuitem_font() perhaps?). Maybe we can even add it as a option in create().

set_font(MenuNew,euTNRItal12) 
set_font(MenuSave,euTNRItal12) 
set_font(MenuCopy,euTNRItal12) 

Indeed, it simply will not work right. Matt or myself will have to implement such functionality into wxEuphoria, which is why I proposed calling the function set_menuitem_font().

Not yet, but I think Matt's been working on it. There were originally some compiling issues since we were still using Watcom. Lately we've been using MinGW and/or GCC which gets around those issues. Honestly, I'd like to rebuild the whole thing using namespaces and separate include files for each major class to keep down the bulk of the library (it's huge!)

Only if you can update the C++ wrappers and euphoria wrappers and rebuild wxEuphoria. It's actually not very difficult (all things considered), but requires a bit of C++ knowledge. The problem is that you have to call a method that's part of the wxMenuItem class which is not currently wrapped.

Actually, the way to go here is probably to update the code for set_font to check the object type passed (wxWidgets has its own built-in RTTI system). Currently, it only operates on wxDC objects, but we could detect wxMenuItem objects and call the appropriate method. The code is in wxGraphics.cpp, if anyone is feeling up to it.

I thought about that. We should probably break it out to handle all the classes that support SetFont() instead of just wxDC.

Mixing third-party libraries with wxEuphoria (or wxWidgets itself) is going to be difficult at best. wxWidgets maintains its own C++ classes derived from wxObject. They are not directly compatible. You should be able to call get_handle() on any wxWindow and pass that through to your third-party library. But wxWidgets may be performing other "magic" in the background that could change the expected behavior of that library. YMMV

Have you tried using wxAUI? (Advanced User Interface) It doesn't allow you full control over the user interface, but it certainly gives you a lot more customization than you would normally have with the vanilla widgets.

I am also working on "themes" for wxAUI, eventually...

Don Phillips' Extra Controls demonstrates this with its "picture menus".

Why not build your application with wxEuphoria as it is, and then set the fonts later?

Personally, I try to focus on the implementation of the program first, not the interface.
