Sam Lantinga 1bfe6d6026 Fixed restoring window size when coming out of fullscreen desktop mode.
Use the style of the window as it will be, not as it currently is at the
time of the AdjustWindowRect call.

Sam Lantinga 54685787ca Fixed bug 3847 - Hit Test x coordinate wrong on secondary monitor
Robert Turner

SDL_windowsevents.c contains code to retrieve the x and y coordinate for a requested hit test. It does this as follows:

    POINT winpoint = { (int) LOWORD(lParam), (int) HIWORD(lParam) };

LOWORD(lParam) does not correctly mask off high bits that are set if the point is on a second (or third, etc.) monitor. This effectively offsets the x-coordinate by a large value.

MSDN documentation suggests that LOWORD() and HIWORD() are the wrong macros for the task, instead suggesting we should be doing something like the following:

    POINT winpoint = { GET_X_LPARAM(lParam), GET_Y_LPARAM(lParam) };

Testing this change on my Windows 10 machine with 2 monitors gives the correct results.

Sam Lantinga 499f928c33 borderless windows will have WM_NCCALCSIZE return 0 for the non-client area. When this happens, it looks like windows will send a resize message expanding the window client area to the previous window + chrome size, so shouldn't need to adjust the window size for the set styles. 2017-09-22 07:15:41 -07:00

- Fixing rendering borderless window. Need to force windows to send a WM_NCCALCSIZE then return 0 for non-client area size.

- Adding WS_CAPTION | WS_SYSMENU | WS_MINIMIZEBOX to borderless windows, for reasons noted in comments.

- Fix SetupWindowData() setting SDL_WINDOW_BORDERLESS. This was being cleared at window creation, causing hanlding for the first WM_NCCALCSIZE message to fail

Sam Lantinga e8059221bd Fixed bug 3806 - Fixes for MSVC compiler warnings
Simon Hug

These are the remaining compiler warnings I see in the current tip cb049cae7c3c.

- SDL_test_log.c defines _CRT_SECURE_NO_WARNINGS without checking if it was already set.

- SDL_windowskeyboard.c converts integers to pointers without going over the (U)INT_PTR types. That bothers MSVC.

Sam Lantinga a4cfa93670 Fixed bug 2293 - Precise scrolling events
Martijn Courteaux

I implemented precise scrolling events. I have been through all the folders in /src/video/[platform] to implement where possible. This works on OS X, but I can't speak for others. Build farm will figure that out, I guess. I think this patch should introduce precise scrolling on OS X, Wayland, Mir, Windows, Android, Nacl, Windows RT.

The way I provide precise scrolling events is by adding two float fields to the SDL_MouseWheelScrollEvent datastructure, called "preciseX" and "preciseY". The old integer fields "x" and "y" are still present. The idea is that every platform specific code normalises the scroll amounts and forwards them to the SDL_SendMouseWheel function. It is this function that will now accumulate these (using a static variable, as I have seen how it was implemented in the Windows specific code) and once we hit a unit size, set the traditional integer "x" and "y" fields.

I believe this is pretty solid way of doing it, although I'm not the expert here.

There is also a fix in the patch for a typo recently introduced, that might need to be taken away by the time anybody merges this in. There is also a file in Nacl which I have stripped a horrible amount of trailing whitespaces. (Leave that part out if you want).

Alexey

Seems to be a missing functionality. I want to set an icon from RC file. I cant pass MAKEINTRESOURCE(X) string to SDL_RegisterApp() cause string returned by MAKEINTRESOURCE string is not actually a string and SDL_strlen will crash. Moreover LoadImage seems to be loading wrong icon size. LoadIcon seems to be fine.

Sam Lantinga 45cec28bc4 Fixed bug 3058 - Slight mistake in GetWindowStyle in SDL_windowswindow.c
Coriiander

There's a slight mistake in the function "GetWindowStyle" found in file "SDL_windowswindow.c".

When a window is marked to be resizable, the resizable style is being added regardless of whether the window has a border or not. While for some arcane, hidden semantics this can be ok, it's still inconsistent in this case.

Sam Lantinga 79a846d486 Fixed bug 3334 - SDL_ShowMessageBox uses wrong index and accesses un-allocated memory
romain.lacroix

For the windows implementation of SDL_ShowMessageBox() : ./src/video/windows/SDL_windowsmessagebox.c:345 WIN_ShowMessageBox()

The implementation in 2.0.4 uses "button index" for parameter "id" of function AddDialogButton().

It then expects the value provided in param wParam of function MessageBoxDialogProc() to be a valid index of a button.

It uses this value to index in the array of buttons when DialogBoxIndirect() returns (line 474 : *buttonid = buttons[which].buttonid;)

However, when dismissing this box with Escape, the return value of DialogBoxIndirect will be SDL_MESSAGEBOX_BUTTON_ESCAPEKEY_DEFAULT (=2) which is not always a valid index of array buttons.

When the array buttons has a length less or equal than 2, the memory access is invalid; I can see that the value written to *buttonId is uninitialized memory (random value).

The fix I propose : use value "buttonid" (field of button) for parameter "id" of AddDialogButton(), then copy return value of DialogBoxIndirect() in *buttonid. This way, we will not use an out-of-bounds index in array buttons.

Sam Lantinga 96305832bc Fixed bug 3702 - Clear error messages of SDL_LoadObject for optional libraries
Simon Hug

Some code in SDL loads libraries with SDL_LoadObject to get more information or use newer APIs. SDL_LoadObject may fail, set an error message and SDL will continue with some fallback code. Since SDL will overwrite the error or exit the function with a return value that indicates success, the error form SDL_LoadObject for the optional stuff might as well be cleared right away.

Sam Lantinga 6e1b11bae4 Fixed bug 3714 - Windows: SDL_WINDOW_FULLSCREEN_DESKTOP broken on 3 monitor setup w/ DPI scaling
Eric Wasylishen 2017-07-26 18:42:58 UTC
I set up an (admittedly exotic) 3-monitor setup, and when I enter fullscreen-desktop on the middle display (#2), the SDL window is off center. (covers half of monitor #2 and most of monitor #3).

The displays are arranged from left to right:

Display #1 (main): 2880x1800, 200% scaling
Display #2: 1920x1200, 150% scaling
Display #3: 1920x1080, 100% scaling

SDL display bounds:
INFO: Bounds: 1440x900 at 0,0
INFO: Bounds: 1281x801 at 1921,0  (these are incorrect)
INFO: Bounds: 1920x1080 at 4800,0

Correct bounds reported by calling EnumDisplayMonitors and printing the LPRECT param of the callback:
1440x900 at (0, 0)
1280x800 at (2880, 0)
1920x1080 at (4800, 0)

It seems like you need 3 displays to reproduce this, and the left two need DPI scaling, and the 3rd display needs to have a different scale factor than the others.

SDL: current hg (11235:6a587b9e0ec8)
Windows 10, Version 10.0.15063 Build 15063
Tested with testdraw2 and testgl2, and pressing alt+enter to enter fullscreen desktop.

This patch reworks SDL_windowsmodes.c to use EnumDisplayMonitors instead of EnumDisplayDevices, so we always have an HMONITOR for each SDL display.

With access to an HMONITOR, we can get the monitor bounds in virtual screen coordinates the proper way, by calling GetMonitorInfo. (whereas the original code was doing some calculations - e.g. "data->DeviceMode.dmPosition.x * data->ScaleX" - to try to get virtual screen coordinates. These worked in simple cases, but failed in more complex cases like this bug)

The one potential problem with my patch is, the ChangeDisplaySettingsEx docs say that you're supposed to get the display name from EnumDisplayDevices, but I'm getting the display name from GetMonitorInfo now.

Sam Lantinga 56363ebf61 Fixed bug 3690 - SDL2 KMS/DRM render context support
Manuel

The attached patch adds support for KMS/DRM context graphics.

It builds with no problem on X86_64 GNU/Linux systems, provided the needed libraries are present, and on ARM GNU/Linux systems that have KMS/DRM support and a GLES2 implementation.
Tested on Raspberry Pi: KMS/DRM is what the Raspberry Pi will use as default in the near future, once the propietary DispmanX API by Broadcom is overtaken by open graphics stack, it's possible to boot current Raspbian system in KMS mode by adding "dtoverlay=vc4-kms-v3d" to config.txt on Raspbian's boot partition.
X86 systems use KMS right away in every current GNU/Linux system.

Simple build instructions:

$./autogen.sh
$./configure --enable-video-kmsdrm

Sam Lantinga a52d48c5ab Fixed bugs 2570, 3145, improved OpenGL ES context support on Windows and X11
Mark Callow

The attached patch does the following for the X11 and Windows platforms, the only ones where SDL attempts to use context_create_es_profile:

- Adds SDL_HINT_OPENGL_ES_DRIVER by which the application can
  say to use the OpenGL ES driver & EGL rather than the Open GL
  driver. (For bug #2570)
- Adds code to {WIN,X11}_GL_InitExtensions to determine the maximum
  OpenGL ES version supported by the OpenGL driver (for bug #3145)
- Modifies the test that determines whether to use the OpenGL
  driver or the real OpenGL ES driver to take into account the
  hint, the requested and supported ES version and whether ES 1.X
  is being requested. (For bug #2570 & bug #3145)
- Enables the testgles2 test for __WINDOWS__ and __LINUX__ and adds
  the test to the VisualC projects.

With the fix in place I have run testdraw2, testgl and testgles2 without any issues and have run my own apps that use OpenGL, OpenGL ES 3 and OpenGL ES 1.1.

Sam Lantinga 4e9c9fce13 Fixed bug 3100 - SetSwapInterval should now be enabled for ANGLE/EGL
Mark Logan 2015-08-24 15:57:50 UTC
In SDL_windowsopengles.c, WIN_GLES_SetSwapInterval is as follows:

WIN_GLES_SetSwapInterval(_THIS, int interval)
{
    /* FIXME: This should call SDL_EGL_SetSwapInterval, but ANGLE has a bug that prevents this
     * from working if we do (the window contents freeze and don't swap properly). So, we ignore
     * the request for now.
     */
    SDL_Log("WARNING: Ignoring SDL_GL_SetSwapInterval call due to ANGLE bug");
    return 0;
}

With a recent version of ANGLE (early July) calling SDL_EGL_SetSwapInterval with a D3D11 backend appears to work just fine. I am working on testing this with D3D9.

--

Alex Szpakowski

I found the bug, it was fixed in 2013. https://bugs.chromium.org/p/angleproject/issues/detail?id=481

In my opinion it should be safe to unconditionally use SetSwapInterval now. Anyone who encounters the bug should update their ANGLE to a version less than 3 years old, especially since they'd be using a SDL version that's 3+ years newer than their ANGLE version.

Sam Lantinga 4a089ca1c8 Fixed bug 3486 - Can't get HINSTANCE of my window
realitix

SDL2 allows to create widow and to get information through SDL_SysWMinfo.
But it misses something, with Vulkan, you need the HWND and HINSTANCE of the window for Win32 system.
Sadly, SDL2 provides only HWND but not HINSTANCE.

In some context, it can be difficult to get the HINSTANCE, indeed, I'm using pySDL2 (Python) and I can only access properties that SDL2 gives me.
I have to use a dirty trick like that to get the HINSTANCE:  (https://raw.githubusercontent.com/bglgwyng/pyVulkan/master/examples/win32misc.py)

Sam Lantinga d5ddb3cb91 Fixed bug 3453 - First mouse button input after a drag and drop event is ignored
Olav Sorensen

After a drag and drop event, any following mouse button input (down/up) doesn't generate an event. Clicking any mouse button a *second* time generates an event like it should.

Further investigation shows that the new SDL_HINT_MOUSE_FOCUS_CLICKTHROUGH logic also causes this issue in other cases, like the first time you open the program and click the mouse.

Sam Lantinga dac3892816 Fixed bug 2832 - Inverted arrow-key navigation in MessageBox
Jan Hellwig

On Windows, you are able to navigate between the buttons on a MessageBox that was created using SDL_ShowMessageBox using the arrow keys. However, if you press the left arrow key, the selection jumps to the button on the right of the currently selected one (and vice versa).

This can be fixed by reversing the order in which the buttons are added to the dialog.

The attached patch files fixes this problem. However the first press of an arrow key leads to the selection of the leftmost or rightmost button on the MessageBox, not to the selection of the button left/right of the one that is selected by default.

Sam Lantinga 7b0ccd32e5 Fixed bug 3405 - Wrong default icon size on windows systems
Evgeny Vrublevsky

Original code in the video/windows/SDL_windowsevents.c registers obsolete WNDCLASS (not WNDCLASSEX). As the result only one icon size is used as the small and normal icons. Also original code doesn't specify required size of an icon. As the result when 256x256 icon is available, the program uses it as a default icon, and it looks ugly.

We have to use WNDCLASSEX and load icons with proper sizes which we can get using GetSystemMetrics.

Better idea. We could use the first icon from resources, like the Explorer does. Patch is included. It also correctly loads large and small icons, so it will look nice everywhere.

Eric Wasylishen

The bug here is that a dead keys pressed before calling SDL_StartTextInput() carries over into future text input, so the next key pressed will have the deadkey applied to it.

This in undesirable, imho, and doesn't occur on OS X (haven't check Linux or elsewhere). It's causing a problem for Quakespasm on German keyboard layouts, where we use the ^ deadkey to toggle the console (which enables/disables text input), and ^ characters are showing up in the TEXTINPUT events.

hit test reported something other than SDL_HITTEST_NORMAL. It lets them know
exactly where in the event queue this happened.

Ryan C. Gordon 8e855f2fbc Added SDL_DROPBEGIN and SDL_DROPCOMPLETE events, plus window IDs for drops.
This allows an app to know when a set of drops are coming in a grouping of
some sort (for example, a user selected multiple files and dropped them all
on the window with a single drag), and when that set is complete.

This also adds a window ID to the drop events, so the app can determine to
which window a given drop was delivered. For application-level drops (for
example, you launched an app by dropping a file on its icon), the window ID
will be zero.

Ryan C. Gordon e346f14277 SDL_WarpMouseGlobal() should return non-void.
There are platforms it isn't implemented on (and currently can't be

This shouldn't break ABI on apps that moved to a revision between 2.0.3 and
2.0.4.

Sam Lantinga 3a08b46336 Fixed bug 2834 - Patch to support dead keys on Windows
Elise Maurer

When inputting text, dead-keys are currently not handled correctly on Windows with the latest SDL2 tip as well as the 2.0.3 release.

Using a French AZERTY keyboard, when I type the `^` key followed by `e` key to compose the `` character, I erroneously get two SDL_TEXTINPUT events, one with the `^` character and one with the `e` character.

I've looked at the history for SDL_windowsevents.c and there's been some back-and-forth with several methods for handling text input:

  * r8142 removed any handling of WM_CHAR because keyboard input was being handled through WM_KEYDOWN along with ToUnicode since r7645.

  * But using ToUnicode actually breaks dead-keys (googling for "ToUnicode dead keys" reports many horror stories of people trying to work around that and failing).

  * It seems like r7645 introduced a double-fix: it fixed WM_CHAR to properly handle Unicode, and also (unnecessarily?) added text input handling to WM_KEYDOWN. Later, r8142 removed the WM_CHAR stuff instead of the WM_KEYDOWN stuff.

The attached patch restores handling of text input through WM_CHAR and removes it from WM_KEYDOWN. I've tested it with French, English and Russian layouts and it seems to do its job. Obviously, with such matters, it's still a risky change.

- do the scancode to keyboard code lookup for the grave key, so that we can show users the correct keyface for the key, rather than forcing it to "`".  Note that if a game is using SDLK_* for its KB mapping then after this change on some keyboards the top left key will no longer be mapped correctly with the old data.

Philipp Wiesemann 8cea1b986e Windows: Fixed crash if initialization of EGL failed but was tried again later. 2015-06-21 19:37:37 +02:00
Philipp Wiesemann 0e45984fa0 Fixed crash if initialization of EGL failed but was tried again later.
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().
