2015-04-10Strip out SDL_VERSION_ATLEAST #ifdef conditionals.Simon Howard
These were added ages ago as hacks to make the code compile with SDL2, back when SDL2 was still in development. They aren't relevant any more and aren't useful - the actual SDL2 port is proceeding on sdl2-branch.
2015-04-10Add missing #includes.Simon Howard
2015-04-04textscreen: Add help URL functionality for windows.Simon Howard
This adds the ability to associate a URL with a window that gives some extra information about it and the configuration options found in it.
2015-03-29textscreen: Remove screen size-based font selection.Simon Howard
This was removed on Windows a while back in favour of a more conservative approach that examined the system DPI settings, but the logic still remained for other systems and it really isn't a good idea. Remove the logic that chooses a large font on large monitors, and add a TODO comment to add proper Linux font selection in the future, based on the Gtk+ HiDPI setting.
2015-02-22Fix mistaken uses of memcpy() on overlapping memory.Simon Howard
The source and destination arguments to memcpy() cannot be overlapping as this is undefined behavior. In these situations memmove() must be used instead, and OpenBSD actually throws an error if this is done. Thanks to ryan-sg for reporting this. This fixes #510.

2014-11-27textscreen: Exit immediately when all windows close.Simon Howard
The main loop should exit when the last window closes, but the loop code was waiting for one event to be received before this took effect. This fixes #474. Thanks to Alexandre-Xavier for the report.
2014-10-19textscreen: Don't allow input of unprintable characters.Simon Howard
If a Unicode character is not part of the Extended ASCII set that we can display on screen, don't allow it to be typed (which would display a backwards question mark). Thanks Alexandre-Xavier for this suggestion on #229.
2014-10-14textscreen: Fix use-after-free with mouse press.Simon Howard
When propagating mouse button presses to widgets within the window, return from MouseButtonPress() immediately, or we will fall through to additional code that references the window structure. If the handler for the widget we clicked on closes the window, this will have been freed. This fixed #439. Thanks to DuClare for telling me about this.

2014-05-05Clean up file headers.Simon Howard
This change rewrites and simplifies the copyright headers at the top of all source files: * Remove "Emacs style mode select" line; this line was included in the headers for the originally released source files and appears to be to set the file type for old versions of Emacs. I'm not sure entirely why it was required but I don't think it is any more. * Remove "You should have received a copy of..." text from copyright header. This refers to the old 59 Temple Place address where the FSF headquarters used to be located and is no longer correct. Rather than change to the new address, just remove the paragraph as it is superfluous anyway. This fixes #311. * Remove ---- separator lines so that the file headers are barer and more simplified.
2014-04-29textscreen: Fix jump when clicking on scrollbars.Simon Howard
Clicking on a scrollbar should scroll the cursor to that location, but the logic for it was buggy because of loss of precision when doing an integer divide. When dividing by bar_max, seek up to the nearest value so that the cursor always arrives where we clicked. Thanks to Alexandre-Xavier for reporting this bug. This fixes #359.
2014-04-12textscreen: Init screen at native bit depth.Simon Howard
Always call SDL_SetVideoMode with bpp=0 to use the desktop's native bit depth, and instead draw into an intermediate 8-bit screenbuffer surface. This ensures that we do not encounter any palette mess-ups as on some systems true 8-bit screen modes are poorly supported.
2014-04-01misc: Fix safe vsnprintf() function.Simon Howard
An off-by-one error in the function caused the strings to be truncated one character too early. Change the return value check so that negative values are also interpreted as indicating truncation; this is the behavior of the Win32 API.
2014-04-01textscreen: Use safe string functions.Simon Howard
Define TXT_{StringCopy,StringConcat,snprintf,vsnprintf} as analogs of the m_misc.c versions so that the textscreen library does not need a dependency on the Doom code, and change all textscreen code to use these instead of unsafe functions. This fixes #372.
2014-03-28textscreen: Add label for PrintScreen key.Simon Howard
Needed to properly fix bug #369.
2014-03-27Define a keyboard scan code for PrintScreen.Simon Howard
There is no real scan code for the PrintScreen key under DOS, but it is convenient to be able to bind it as a screenshot key. Define a "fake" scancode (126) to represent PrintScreen so that it can be represented as a key binding in configuration files. Also add some comments/notes to the scantokey[] lookup table. This fixes #369.
