Global attributes are not associated with any particular element. They represent and affect the global behavior of the toolkit.
To access global attributes use the IupGetGlobal and IupSetGlobal functions. In Lua global attributes can only be accessed trough those functions. In C, the functions IupGetAttribute and IupSetAttribute can also be used if you set the element handle to NULL.
The language used by some pre-defined dialogs.
Can have the values ENGLISH and PORTUGUESE. Default: ENGLISH. Can also be set by IupSetLanguage.
Returns the name of IUP's version.
The value follows the "major.minor.micro" format, major referring to broader changes, minor referring to smaller changes, and micro referring to corrections only. Ex.: "1.7.2".
Returns the IUP's copyright.
Ex: "Copyright (C) 1994-2014 Tecgraf/PUC-Rio".
Informs the current driver being used.
Two drivers are available now, one for each platform: "GTK", "Motif" and "Win32".
When the last visible dialog is closed the IupExitLoop function is called. To avoid that set LOCKLOOP=YES before hiding the last dialog. Possible values: "YES" or "NO". Default: "NO".
If an error is found, returns a string with the system error description.
By default IUP uses strings in the current locale (See FONT attribute). To use UTF-8 strings set this attribute to Yes. Default: NO.
By default IUP uses file names in the current locale, even when UTF8MODE=Yes. To use UTF-8 file names set this attribute to Yes. Default: NO.
The default number of decimal places used in floating point output by some controls (IupMatrixEx and IupGetParam). Local attributes may overwrite the default. Default: 2.
Symbol used for decimal separator in numeric values used in floating point output by some controls (IupMatrixEx, IupGetParam and IupPlot). Can be "." or "," only. Default uses the one defined by the system locale.
Force the display of images in menus. Default: Yes
Allow the overlay scrollbar in IupCanvas to use a minimum space. By default IUP will use a regular scrollbar space even when overlay scrollbar is enabled in the system.
Flag indicating that GTK is using a global menu instead of a per window menu. See more information at the GTK driver documentation.
Flag to enable the global keys Alt+Ctrl+Shft+L to display the IupLayoutDialog.
Flag to enable the global keys Ctrl+'+' and Ctrl+'-' that change the FONTSIZE and refresh the layout of the dialog. If element sizes are NOT set using RASTERSIZE their sizes will be automatically increased and decreased. Images are not changed.
Automatically scale all images, except stock images, by a given real factor. If "DPI" value is used then the factor will be automatically calculated from the ratio between screen resolution and IMAGESDPI. Only images with BPP > 8 are scaled.
Defines the resolution of the images of the application. Common values are 96, 144, 192, and 288 DPI. Default: 96. Used when IMAGEAUTOSCALE=DPI.
Force a size for stock images by controlling the image height. If that image size is not available the stock image is resized to match the given size. By default the size will be automatically calculated from the screen resolution: if res <= 96 DPI then size = 16, if 144 DPI size = 24, if 192 DPI size = 32, else size = 48. Only images with BPP > 8 are scaled.
If defined allow IUP to be used inside coroutines in Lua.
Restricts the number of instances of the application by using a name to identify it. The value must also be a partial match to the title of a dialog that will receive the COPYDATA_CB callback with the command line of the second instance. When consulted returns NULL if inside the second instance. So usually in the application initialization after IupOpen, set SINGLEINSTANCE and then consult its value, if NULL abort the second instance by calling IupClose and returning from main.
Controls and returns the cursor position in absolute coordinates relative to the origin of the main screen. The origin of the main screen is at the upper left corner, in Windows it is affected by the position of the Start Menu when it is at the top or left side of the screen. Accept values in the format "XxY" (in C "%dx%d), example "200x200". In GTK and Motif also generates mouse motion messages. (since GTK 2.8)
Simulates a mouse button press, release or motion at the given coordinates. The position is in absolute coordinates relative to the upper left corner of the screen. Accept values in the format "XxY button state" (in C "%dx%d %c %d"), example "200x200 1 1". button can be one of the IUP_BUTTON1,... definitions. state can be 2=double click, 1=pressed, 0=released, or -1=motion. The cursor position is always updated. In Windows button can be 'W' and state=delta, so a wheel button scroll is simulated.
IMPORTANT: not fully working. In Windows and GTK, menu items are not activated. Although submenus open, menu items even in the menu bar are not activated. In Windows, inside the IupFileDlg dialog, clicks in the folder navigation list are not correctly interpreted. In Motif click and drag operations are not performed.
Returns the state of the Shift keys (left and right). Possible values: "ON" or "OFF".
Returns the state of the Control keys (left and right). Possible values: "ON" or "OFF".
Returns the state of the keyboard modifier keys: Shift, Ctrl, Alt and sYs(Win/Apple). In the format of 4 characters: "SCAY". When not pressed the respective letter is replaced by a space " ".
Sends a key press message to the element with the focus. The value is a key code. See the Keyboard Codes table for a list of the possible values.
Sends a key release message to the element with the focus. The value is a key code. See the Keyboard Codes table for a list of the possible values.
Sends a key press and a key release messages to the element with the focus. The value is a key code. See the Keyboard Codes table for a list of the possible values.
Turns on/off ("YES" or "NO") the auto-repeat of keyboard keys in the whole system. May be used as an optimization in high performance applications.
Turns on/off ("YES" or "NO") the global callbacks used to intercept global mouse and keyboard events. The callbacks must be set using the IupSetFunction function using the following names: GLOBALKEYPRESS_CB, GLOBALMOTION_CB, GLOBALBUTTON_CB and GLOBALWHEEL_CB (Windows Only). Their parameters are the same as the standard callbacks, but without the Ihandle* parameter.
In Lua use the iup.SetGlobalCallback(name, func) function. (since 3.7)
Informs the current operating system. On UNIX, it is equivalent to the command "uname -s" (sysname). On Windows, it identifies if you are on Windows 2000, Windows XP or Windows Vista. Some known names:
Notice that "Windows 8.1" will normally be detected as "Windows 8", unless a special Manifest is used. See MSDN for more information.
Informs the current operating system version number.
On UNIX, it is equivalent to the command "uname -r" (release). On Windows, it identifies the system version number and service pack version. On MacOSX is system version.
Returns a text with a description of the system language.

Returns the screen depth in bits per pixel.
Returns a real value with the screen resolution in pixels per inch (same as dots per inch - DPI).
Indicates if the display allows creating TrueColor (> 8bpp) IupCanvas controls, even if PseudoColor is the default, i.e. even if SCREENDEPTH<=8 . Returns "YES" or "NO". Usefull in Motif.
