* Improve horizontal interactive selection
* Using half-character positions to implement selection
similar to Fl_Input.
* Add word and line selection
* Fix vertical position of text
Clear was setting characters to a space using the current style,
but if the style left Dim/Bold/Inverse (etc) enabled, that was being
used to affect the clear character, and thus affected clearing screen.
Seems weird tho; what if one wants to do a cleol (\033[K) on a screen
that is all inverted text; is there no way to use inverse mode for
clearing to the end of line? Or to delete a character?
Fixed a bug in the handling of xterm color 39 + 49, which avoids
applying Dim/Bold if default color is the special "see through" color
0xffffff00. A test will be added to test/terminal to excercise this
in a follow up commit.
Renamed CharStyle::?gcolor_uchar() -> CharStyle::?gcolor_xterm()
for a consistent naming convention.
Changed fltk_fg_color() from a static func to a CharStyle method
because it needs to access the defaultcolor for the special cases
for xterm colors 39 and 49.
Made CharStyle::attr_color() private, as per Jonathan Griffitts request
in issue #909.
Improved docs regarding effects of Dim/Bold for xterm and non-xterm color
methods.
Fl_Terminal::text?gcolor_xterm() methods now use CharStyle::?gcolor_xterm()
methods, removing the duplicate code logic.
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_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.
This addresses some issues pointed out by GitHub Issue #875.
Documentation lacked details about Fl_Multi_Label assignment and
correct memory handling.
The new methods
- Fl_Menu_Item::image_label(const Fl_Image *) and
- Fl_Menu_Item::multi_label(const Fl_Multi_Label *)
provide a cleaner interface to assign images and Fl_Multi_Label's
to menu items.
examples/howto-menu-with-images.cxx: carify some issues, fix leak,
and use new Fl_Menu_Item::multi_label(const Fl_Multi_Label *).
This library is no longer needed in FLTK itself. There is only one
demo program (test/forms.cxx) that uses it if it is built. The demo
program displays a message if fltk_forms is not available.
The default is 'enabled' for backwards compatibility but this may
be changed to 'disabled' in a future version.
- the current UI for fallback/default/original shortcut was
confusing, so I remove it until we find something better. I
kept the values so we can reinstate a better interface without
changing the API.
- add fl_draw_radio(...) to standardize radio button drawing
- src/Fl_Light_Button.cxx: use fl_contrast() to determine color of
radio button and check (light) button check marks, and use
new fl_draw_radio() method
- src/Fl_Menu.cxx: same as src/Fl_Light_Button.cxx and use
fl_draw_check() instead of "manually" drawing the check mark
(forgotten in an earlier update)
- add Fl::args_to_utf8() to convert commandline arguments to UTF-8
This new function closes the gap that previously only Visual Studio
applications converted their commandlines to UTF-8.
Tested with MinGW, MSYS2/MinGW-w64, and Visual Studio (2019).
- some documentation missing
- Fl_Tile::resize() not satisfying yet
- minimums work, maximums currently ignored
- 0 size children may make program hang
Although this was not strictly necessary I decided to implement the
proposed patch, but in a slightly different way.
This adds a static public method for internal use only but it wouldn't
do any harm if a user called it.
New public methods:
void clear(void);
void clear(Fl_Color val);
old protected methods made public:
void clear_screen(bool scroll_to_hist=true); // ESC [ 2 J
void clear_screen_home(bool scroll_to_hist=true); // ESC [ H ESC [ 2 J
void cursor_home(void); // ESC [ 0 H
test/terminal modified to test these, and added separate tests
for both the API and ANSI code ways to do these ops.
textcolor() needed for consistency, color() behavior documented.
Both added to the test/terminal app.
Elaborated on the special background "see through" color value + behavior,
tested with color() in test/terminal app.
User can now drag widgets from the toolbox into the grid
or use the context menu to add them into the corresponding
cell. If no position is indicated, now children are added at the
first free cell.
- add CMake option 'OPTION_USE_STD'
- add configure option '--enable-use_std'
- move FL/Fl_String.H to src/Fl_String.H
- move FL/Fl_Int_Vector.H to src/Fl_Int_Vector.H
- remove Fl_String from demo program examples/callbacks.cxx
- remove Fl_Int_Vector from public header FL/Fl_Table.H
- some methods of Fl_Table are no longer inline
- add CMake option OPTION_USE_STD to allow std::string in some
selected functions and methods
Experimental, may be removed before release:
- use either Fl_Int_Vector or std::vector in Fl_Table depending
on CMake OPTION_USE_STD or configure --enable-use_std
Move all fl_filename* functions that use Fl_String to fluid
Main changes in fluid:
- add fluid_filename.h and .cxx
- include "fluid_filename.h" rather than <FL/filename.H>
Update fl_input(), fl_password() and test/ask
- add maxchar parameter to fl_input() and fl_password()
- fl_input_str() and fl_password_str() are optional and return
std::string if enabled (FLTK_USE_STD)
- FL/Fl_Grid.H: header file
- src/Fl_Grid.cxx: implementation
- examples/grid-simple.cxx: simple example program
- test/cube.cxx: use Fl_Grid for layout
- test/grid_alignment.cxx: test cell alignment and other functions
- test/grid_buttons.cxx: demo program as discussed in fltk.general
- test/grid_login.cxx: like test/flex_login.cxx but with Fl_Grid
- test/flex_login.cxx: modified to match test/grid_login.cxx
- remove static variables and functions
- make move_intersection() virtual
- add (protected) cursor access methods
These changes were inspired by STR 2791 where the user proposing an
enhancement was not able to subclass Fl_Tile properly. This commit
fixes the mentioned issues and enables subclassing without copying
internal code.
... "when there's no current window".
Silently ignore GLUT function calls that need a current window if the
current window is NULL, return 0 from functions that return an 'int'.
Check if window is shown in Fl_X11_Gl_Window_Driver::swap_buffers().
This would issue "XRequest.nnn: GLXBadDrawable 0x0" on X11 otherwise.
Note: the chosen implementation to ignore GLUT calls silently appears
to be compatible with GLUT (3.7) whereas FreeGLUT 3.0 would issue error
messages and exit. The latter could be implemented as well but would
be much more work.
The user can add an arbitrary number of highly configurable
shell commands through the setting panel. The commands can
be saved as user preferences, inside the .fl file, or exported
to an external file. Shell scripts can be limited to individual
platforms, can have shortcut keys, etc. .
* documentation will follow
* support to call `fltk-config` will follow
Todo: fluid-shared can't (yet) be built agains the shared fltk lib
because of some linker errors. Needs investigation.
Note: fluid-shared is basically a test program to demonstrate linking
against the shared FLTK libs but doesn't work yet using VS (MSVC).
This is no problem for the functionality.
