request to close the dialog

Object is visible but inactive

Object makes the dialog exit

Mouse is on top of object

Reserved for internal use

this object wants the input focus

This constant gives a ratio which can be used to convert a fixed point number in binary angle format to a fixed point number in radians.

magic number for autodetect

Allegro will try to set the specified resolution with the current color depth in fullscreen mode.

Allegro will try to set the specified resolution with the current color depth in a windowed mode.

Indicates that the al_request_scroll and al_poll_scroll functions may be used with this driver.

The regular fullscreen DirectX driver, running with hardware acceleration enabled.

Simplified fullscreen DirectX driver that doesn't support any hardware acceleration, video or system bitmaps, etc.

The regular windowed DirectX driver, running in color conversion mode when the color depth doesn't match that of the Windows desktop.

The windowed GDI driver.

Indicates that the opaque version of the al_rectfill function, the al_clear_bitmap routine, and al_clear_to_color, are implemented using a hardware accelerator.

Indicates that the solid and masked pattern modes of the al_rectfill function is implemented using a hardware accelerator (see AL_GFX_HW_FILL).

Indicates that monochrome character expansion (for text drawing) is implemented using a hardware accelerator.

Indicates that the copy pattern modes of the al_hline function, and any other functions that use it as a workhorse, are implemented using a hardware accelerator (see AL_GFX_HW_HLINE).

Indicates that the XOR version of the al_hline function, and any other functions that use it as a workhorse, are implemented using a hardware accelerator (see AL_GFX_HW_HLINE).

Indicates that the XOR version of the al_line and al_vline functions are implemented using a hardware accelerator.

Indicates that the al_masked_blit and al_draw_sprite functions are being accelerated in hardware when the source image is a memory bitmap and the destination is the physical screen.

Indicates that the al_masked_blit and al_draw_sprite functions are being accelerated in hardware when the source image is a system bitmap and the destination is the physical screen.

Indicates that the al_masked_blit routine is capable of a hardware accelerated copy from one part of video memory to another, and that al_draw_sprite will use a hardware copy when given a sub-bitmap of the screen or a video memory bitmap as the source image.

No graphics mode.

Uses the SVGAlib library for graphics output.

Closes any previously opened graphics mode, making you unable to use the global variable al_screen, and in those environments that have text modes, sets one previously used or the closest match to that (usually 80x25).

Uses direct hardware access to set standard VGA resolutions, supporting the same modes as in the DOS version of this driver.

The same as AL_GFX_XDGA2, but turns off hardware acceleration support.

The same as AL_GFX_XWINDOWS, but while AL_GFX_XWINDOWS runs windowed, this one uses the XF86VidMode extension to make it run in fullscreen mode even without root permissions.

Attempts to autodetect your joystick hardware.

Regular joystick interface.

Use the regular Win32 interface rather than DirectInput to access the joystick.

Key scan-code identifiers.

Maximun number of elements.

ALSA RawMIDI driver.

Identifier to pass to al_install_sound.

Open Sound System.

Max number of MIDI voices.

Selects the custom Allegro cursor, i.e.

The operating system default `busy' cursor (hourglass).

Indicates that the mouse cursor is the default system cursor, not Allegro's custom cursor.

other keyboard input

double click on the object

dialog is finished - cleanup

keyboard shortcut

mouse moved away from object

mouse left button released

mouse middle button released

mouse right button pressed

does object want the mouse?

broadcast character to all objects

Defined to TRUE if current version is a BETA version.

Defined to a text string containing all version numbers and maybe some additional text.

When used in combination with the loop flag, causes the sample to change direction each time it reaches one of the loop points, so it alternates between playing forwards and in reverse.

Loops repeatedly through the sample, jumping back to the loop start position upon reaching the loop end.

An affine texture mapped polygon.

Like AL_POLYTYPE_ATEX, but al_bitmap_mask_color texture map pixels are skipped, allowing parts of the texture map to be transparent.

Like AL_POLYTYPE_ATEX_TRANS, but al_bitmap_mask_color texture map pixels are skipped, allowing parts of the texture map to be transparent.

A simple flat shaded polygon, taking the color from the `c' value of the first vertex.

A gouraud shaded polygon which interpolates RGB triplets rather than a single color.

A perspective-correct texture mapped polygon.

Like AL_POLYTYPE_PTEX, but al_bitmap_mask_color texture map pixels are skipped, allowing parts of the texture map to be transparent.

Like AL_POLYTYPE_PTEX_TRANS, but al_bitmap_mask_color texture map pixels are skipped, allowing parts of the texture map to be transparent.

Used for z-buffered mode.

Defined to the middle version of Allegro.

DirectX system driver.

Tells to al_install that must install a stripped down version of Allegro that won't even try to touch the hardware or do anything platform specific: this can be useful for situations where you only want to manipulate memory bitmaps, such as the text mode datafile tools or the Windows GDI interfacing functions.

Fixed size, 8-bit ASCII characters.

Current encoding.

Variable size, UTF-8 format Unicode characters.
