I'm taking a page from Dolphin's book, and including copies of each dependency's source code. This combines the ease of use of including pre-built libraries instead of needing to navigate a package manager - as is (or was) the case for MSVC - with the portability of using packages. Granted, this method's more of a jack of all trades, master of none, since it's *less* user-friendly than prebuilt packages (compilation times), and you don't get the per-distro compatibility fixes you'd get from a package manager. You can still use system libs if you want. In fact, it's still the default behaviour: compiling the libs manually is just a fallback. I'll add an option to force-enable this soon, however, since it's a nicer way to produce static MSYS2 builds than the hackish nightmare that I was using before. Not to mention, having my own copy of the sources means I can provide my own fixes and tweaks your package manager may not. For example, I can combine MSYS2's FreeType subpixel rendering with vcpkg's fix for SDL2 exporting its symbols in static builds.

/**
|
|
This is a button that when pushed pops up a menu (or hierarchy of
|
|
menus) defined by an array of
|
|
Fl_Menu_Item objects.

|
|
<P>Normally any mouse button will pop up a menu and it is lined up
|
|
below the button as shown in the picture. However an Fl_Menu_Button
|
|
may also control a pop-up menu. This is done by setting the type().
|
|
If type() is zero a normal menu button is produced.
|
|
If it is nonzero then this is a pop-up menu. The bits in type() indicate
|
|
what mouse buttons pop up the menu (see Fl_Menu_Button::popup_buttons). </P>
|
|
<P>The menu will also pop up in response to shortcuts indicated by
|
|
putting a '&' character in the label(). </P>
|
|
<P>Typing the shortcut() of any of the menu items will cause
|
|
callbacks exactly the same as when you pick the item with the mouse.
|
|
The '&' character in menu item names are only looked at when the menu is
|
|
popped up, however. </P>
|
|
|
|
When the user clicks a menu item, value() is set to that item
|
|
and then:
|
|
|
|
- The item's callback is done if one has been set; the
|
|
Fl_Menu_Button is passed as the Fl_Widget* argument,
|
|
along with any userdata configured for the callback.
|
|
|
|
- If the item does not have a callback, the Fl_Menu_Button's callback
|
|
is done instead, along with any userdata configured for it.
|
|
The callback can determine which item was picked using
|
|
value(), mvalue(), item_pathname(), etc.
