SDL2 Considerations
===================
Most of the information in the [SDL Considerations](sdl.md) document is also
valid for the SDL2 platform. This document describes the differences.
Integration with SDL2
---------------------
As mentioned in the [SDL Considerations](sdl.md) document, the SDL port uses
the following variables:
SDL_Surface *pdc_screen, *pdc_font, *pdc_icon, *pdc_back;
int pdc_sheight, pdc_swidth, pdc_yoffset, pdc_xoffset;
The SDL2 port adds:
SDL_Window *pdc_window;
These can be used or modified in your own code. Like the `pdc_screen` variable
used by the SDL port, you can initialize `pdc_window` in your own code. See the
sdltest demo for an example. If it's not initialized, PDCurses will do it for
you. If PDCurses initializes `pdc_window`, it will clean up/deallocate these
variables on exit.
Fonts
-----
If the `PDC_WIDE` flag is set during compilation, SDL2_ttf is used to render
fonts. This allows for use of a full UCS-2 (16 bit Unicode) character set.
Using SDL2_ttf adds:
TTF_Font *pdc_ttffont;
int pdc_font_size;
The default TrueType font can be modified by setting a define during compile
time (e.g. `-DPDC_FONT_PATH=/usr/share/fonts/truetype/dejavu/`). This can be
overridden by initializing `pdc_ttffont` in your own code. Similar
to the `PDC_FONT` environment variable for bitmap fonts, one can also override
TTF fonts using the `PDC_FONT` environment variables. Unless modified during
compile time, the defaults are:
Windows: C:/Windows/Fonts/lucon.ttf
OS X: /Library/Fonts/Courier New.ttf
Other: /usr/share/fonts/truetype/freefont/FreeMono.ttf
Font size can be set using the `PDC_FONT_SIZE` environment variable or by
setting the value of `pdc_font_size` in your own code. The default size is 18.
Clipboard
---------
SDL2 port uses functionality provided by the SDL2 clipboard functions to add
basic clipboard support.
