This adds a new shortcut (Ctrl+R) which toggles the resizable state of
the window and allows the user to lock the window size and prevents
resizing.
Closes bug:15124.
Init ImGui after our GLContext object has been initialized and check the
context type to specify the proper GLSL version.
Also make sure we are not in GLES mode before setuping ImGui.
The "scale_factor" setting can be -1, which means the default. But
instead it was hardcoded to 1, which is wrong for the SurfaceSDL
graphics mode where the default is 2.
Normally when using the OpenGL mode the window is not resized when
starting a game, unless the game requires a window bigger than the
current window size. However this was not the case if the engine
called initSizeHint() with sizes smaller than the current window
size, as in this case the window was forcibly resized to the bigger
of those provided sizes.
The initSizeHint() function was added for engines that use multiple
resolutions to indicate when starting the engine that it may use
multiple resolutions and thus may need a bigger window later than
when the game starts. This allows getting the bigger size from the
start and prevent window resize during gameplay. But this function
was not meant to make the window smaller if the graphics backend
request an even bigger size, which may be the case of the OpenGLSDL
graphics backend as it tries to preserve the current window size.
This unifies the ImGui processing for both 2D and 3D engine.
This also make sure we don't destroy ImGui if init failed (like on older
OpenGL).
The destroy callback is also called whenever we destroy the context.
Using the Ctrl+Alt+0 or 9 keymap
Also added a guard check for kFeatureScalers to allow the actions (kActionNextScaleFilter, kActionPreviousScaleFilter) to change scaler (but not scaler factor) in sdl/sdl-graphics.cpp
The mouse position is set in window coordinates, but it's clipped to the
game area in drawable area coordinates. Previously, the scaling between
these two was not taken into account when calculating the right/bottom
edges of the game area. When the clipped mouse position was converted
back to window coordinates and rounded to the nearest integer, it could
end up on the edge of the game area, not inside of it. This leads to a
loop in which the clipped mouse position is outside of the game area and
needs to be clipped again.
This fixes bug #12646.
The previous SdlGraphics3dManager::toggleFullScreen() was not using
beginGFXTransaction / endGFXTransaction in toggleFullScreen().
Restore this logic for 3D games, as using transactions in such games
results in a black screen for 3D games when switching to full screen
A regression from d33487f64
SDL handles HiDPI scaling differently depending on the system. On
macOS for example the SDL window size and SDL drawable area have a
different size (factor 2 usually) while on Windows they are the
same. When HiDPI is disabled (for the SDL Surface mode for example)
they are always the same.
We need to appl this scaling when converting cursor position between
the drawable area and the SDL window.
The OpenGLSdlGraphics3dManager::getSupportedFormats() implementation
returns an empty list. This caused a crash when trying to get the
first element of the list in SdlGraphicsManager::setState().
This fixes bug #12762: The longest Journey crashes
