This is useful if FLTK is built as a subproject, for instance by
using FetchContent.
|
|
|
|
Also: set build requirement of OpenGL3 tests to C++11 to enable
building in C++98 mode (if the compiler allows C++11).
Note: this may be removed in 1.5.0 when FLTK requires C++11 anyway.

Improve recognition of Wayland and X11 specific build options and
remove duplicates from required dependencies (FLTK_LDLIBS) used in
fltk-config.
This should also fix the GitLab CI build process.
To do: the logic to find the dependencies of Wayland and X11 is
currently suboptimal. This will be improved in a later commit.

Restore "too much optimized" CMake code.
The issue would only be visible if neither FLTK_GRAPHICS_CAIRO nor
FLTK_BACKEND_WAYLAND was active.

- GitHub CI: fix wrong CMake option name
- fl_add_library: disable debug output (MSVC), fix formatting
|
|
This is a big commit and there are too many changes to list them all.
The main changes are:
- rename all CMake build options to 'FLTK_*'
- export library targets with namespace (prefix) 'fltk::'
- standardize shared library target names with suffix '-shared'
- set public build properties on libraries for consumers
- document library names and aliases in README.CMake.txt
- document changes in "Migrating Code from FLTK 1.3 to 1.4"
- partial backwards compatibility for old user projects
Included but not directly related changes:
- fix Windows (Visual Studio) DLL build
- add CMake function fl_debug_target() to show target properties
- don't build test programs if FLTK is a subproject
- internal: reformat CMake code: remove space before '('
Thanks to Matthias and Manolo for their help, testing, and feeback.

Fl_Screen_Driver::screen_boundaries_known()
Fl_Window_Driver::set_popup_window() is to be used to declare a window should be
positioned relatively to a previously mapped other window. This allows a platform
to process such windows differently from other windows if needed.
Menu and tooltip windows are so declared.
A call to Fl_Window_Driver::set_popup_window() also allows to distinguish a real
menu or tooltip window from a window marked by Fl_Window::set_menu_window()
or by Fl_Window::set_tooltip_window() but that's not a real menu or tooltip.
New member function bool Fl_Screen_Driver::screen_boundaries_known() returns
true by default. A platform where the position of windows inside a screen is hidden
(e.g., Wayland) returns false. This allows FLTK to refrain from trying to make sure
a computed position is inside a screen.

Document restrictions imposed by the new system file chooser dialogs,

When an Fl_Text_Editor ended up under the mouse, it took
mousewheel events for itself, freezing navigation of a
parent's Fl_Scroll.
Patch handles mousewheel events for both up/down and left/right
by checking:
> If editor has no scrollbar (e.g. no content to scroll to),
then mousewheel events for that scrollbar are ignored
so the parent can be navigated.
> If editor has a scrollbar, it handles wheel events until scroller reaches
an extreme position (e.g. top or bottom), it starts ignoring wheel events
so the parent can be navigated.

Without the '/' FLTK 1.4 wouldn't fall back to the 1.3 prefs folder
even if it existed.

Fixes also a similar crash occuring after use of set_tooltip_window().
Two bool member variables are added to class Fl_Window_Driver
to indicate true FLTK menu windows (i.e., created by Fl_Menu_Item::pulldown())
and true FLTK tooltip windows (i.e., Fl_Tooltip).

'buf' could indeed be used uninitialized if the switch statement
below was executed with an unknown style (no default case).
