Global Attributes

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 C, the functions IupGetAttribute and IupSetAttribute can also be used if you set the element handle to NULL.

General

LANGUAGE

The language used by some pre-defined dialogs.

Can have the values ENGLISH, PORTUGUESE, SPANISH, CZECH, RUSSIAN, GERMAN, FRENCH, CHINESE, JAPANESE or ITALIAN. Default: ENGLISH. It can also be set by IupSetLanguage.

VERSION (read-only)

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".

COPYRIGHT (read-only)

Returns the IUP's copyright.

Ex: "Copyright (C) 1994-2014 Tecgraf/PUC-Rio".

DRIVER (read-only)

Informs the current driver being used.

Available drivers: "Win32", "WinUI", "GTK", "GTK4", "Motif", "Qt", "FLTK", "EFL", "Cocoa", "CocoaTouch", "Android" and "Haiku".

APPID

Application identifier used by the desktop environment. In GTK/Wayland, it maps to the XDG desktop file ID. On Haiku, it becomes the BApplication MIME signature. Also used by IupConfig as a last fallback when neither APP_NAME nor APPNAME is set. On X11 it is the WM_CLASS instance name, and on Wayland the application id. Can be set once. Used by the desktop environment in GTK, GTK 4, Qt, FLTK, EFL, Motif and Haiku; only stored in the other drivers. When not set, GTK, GTK 4, Qt, FLTK, EFL and Motif use the executable name. On Android it is read-only and reflects the app's manifest application id. On iOS, it is read-only and reflects CFBundleIdentifier from the app's Info.plist.

APPNAME

Application name used by the system. In Windows, it is used for the taskbar and tray. In macOS, it is used for the dock. Also used by IupConfig as a fallback when APP_NAME is not set (APPNAME is checked first, then APPID). On X11 it is the WM_CLASS class name, except in GTK 4, which always uses the instance name, and in FLTK, which uses the capitalized instance name. Used by the system in Win32, WinUI, macOS, Qt, GTK, EFL and Motif; only stored in the other drivers. On Android it is read-only and reflects the app's manifest label. On iOS, it is read-only and reflects CFBundleDisplayName (or CFBundleName if not set) from the app's Info.plist.

System Control

LOCKLOOP

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".

EXITLOOP

Disable the IupExitLoop function when IupMainLoopLevel is 1. Used when the application runs secondary dialogs that behave as full applications but sharing the same IUP environment. Possible values: "YES" or "NO". Default: "YES".

CUSTOMQUITMESSAGE [Windows Only]

Enable a custom quit message instead of using WM_QUIT.

LASTERROR [Windows Only] (read-only)

If an error is found, returns a string with the system error description. Available in Win32 and WinUI.

UTF8MODE

By default, IUP uses strings in the current locale (See FONT attribute). To use UTF-8 strings, set this attribute to YES. Default: NO. Not supported in iOS.

UTF8AUTOCONVERT

The inverse of UTF8MODE. Default: YES. Supported in GTK, GTK 4, Qt, FLTK, WinUI, macOS, iOS, Haiku and WebAssembly.

UTF8MODE_FILE [Win32 and Motif Only]

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 main places affected by this attribute are IupFileDlg attributes, such as VALUE, FILE and DIRECTORY, and the DROPFILES_CB callback.

Notice that IUP use the fopen based functions to read and write files. In Windows fopen expects the filename string in the ANSI encoding by default. If your filename, including the path, has characters that cannot be converted to ANSI, fopen will fail to open the file. In Windows, we could use _wfopen combined with UTF-8, but this is a Microsoft only function and most of fopen usage in these libraries are in portable modules. This is an IUP limitation in Windows.

The simple workaround is to not use special characters in folders or files name in Windows... Legacy applications will also have the same problem.

Another option is to call:

 setlocale(LC_ALL, ".UTF8"); 

But it will work for fopen only in Visual Studio 2017 or newer Microsoft compilers (setlocale will return NULL on other compilers). fopen will successfully open the file if the filename is a UTF-8 string with special characters. So you will be able to set both UTF8MODE and UTF8MODE_FILE to YES.

If you decide to use this feature, another interesting option is to set the console code page to UTF-8 executing "chcp 65001" on the command line. This will allow your printf output to be properly displayed when using UTF-8 strings. This feature actually works for all Microsoft compilers in Windows, and for MingW, even when setlocale returns NULL. Notice that some font packages must be installed for this to fully work for all characters (for instance, Chinese, Japanese and Korean, along with some symbols too).

As a complement, from fopen documentation in MSDN: "You can use either forward slashes (/) or backslashes (\) as the directory separators in a path".

DEFAULTPRECISION

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.

DEFAULTDECIMALSYMBOL

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.

SB_BGCOLOR [GTK, GTK 4 and Motif Only]

By default, the scrollbars will not be affected by the BGCOLOR in native controls. If set to YES, the system will try to render scrollbars in the same color of the BGCOLOR, but notice that this may affect scrollbars visibility. This affects IupCanvas, IupList, IupText and IupTree.

SHOWMENUIMAGES

Force the display of images in menus. Default: YES. Supported in GTK, GTK 4, Qt, EFL and WinUI.

OVERLAYSCROLLBAR [GTK, GTK 4 Only]

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.

GLOBALMENU [GTK Only]

Flag indicating that GTK is using a global menu instead of a per window menu.

GLOBALLAYOUTRESIZEKEY

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.

IMAGEAUTOSCALE

If defined, 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. The minimum resulted size when automatically resized is 24 pixels height.

IMAGESDPI

Defines the resolution of the images of the application. Common values are 96, 144, 192, and 288 DPI. Default: 96. Used when IMAGEAUTOSCALE=DPI.

IMAGESTOCKAUTOSCALE

Stock images are automatically scaled by default. Default: YES.

IMAGESTOCKSIZE

Force the 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 <= 144 DPI size = 24, if 192 DPI size = 32, else size = 48. The minimum resulted size when automatically resized is 24 pixels height.

TREEIMAGE24

Forces the 24x24 default images in IupFlatTree. Default: NO.

PROCESSWINDOWSGHOSTING [Windows Only]

If set to NO will disable the window ghosting feature for the duration of the process, cannot be enabled again. When disabled, the application dialogs cannot be moved or resized while application that is not responding, also the "Not Responding" display at the application tittle bar will not be done anymore.

SINGLEINSTANCE

Restricts the number of instances of the application by using a name to identify it. The first dialog that has a COPYDATA_CB callback will receive 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.

In Windows (Win32 and WinUI) uses a named mutex for detection and WM_COPYDATA for communication. In Linux/Unix (GTK, GTK4, Qt, Motif, FLTK, EFL) uses D-Bus session bus name ownership. In macOS uses CFMessagePort. In Haiku uses a named-port rendezvous. On Android single instance is enforced by the Activity launchMode in the manifest, so the SINGLEINSTANCE attribute and COPYDATA_CB are not implemented. Not supported in iOS and WebAssembly.

System Mouse and Keyboard

CURSORPOS

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 top-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.

MOUSEBUTTON (write-only)

Simulates a mouse button press, release or motion at the given coordinates. The position is in absolute coordinates relative to the top-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.

SHIFTKEY (read-only)

Returns the state of the Shift keys (left and right). Possible values: "ON" or "OFF".

CONTROLKEY (read-only)

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.

KEYRELEASE (write-only)

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.

KEY (write-only)

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.

AUTOREPEAT [Motif, FLTK and EFL Only]

Turns on/off ("YES" or "NO") the auto-repeat of keyboard keys in the whole system. It May be used as an optimization in high performance applications.

SHORTCUTKEY [Haiku Only] (read-only)

Primary shortcut modifier from the active Haiku keymap: "CTRL" (Windows-style) or "ALT" (BeOS default).

INPUTCALLBACKS

Turn 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.

System Information

SYSTEM (read-only)

Informs the current operating system. On UNIX, it is equivalent to the command "uname -s" (sysname). Some known names:

• "macOS"
• "iOS"
• "Android"
• "FreeBSD"
• "Linux"
• "SunOS"
• "Solaris"
• "AIX"
• "HP-UX"
• "WinXP"
• "Vista"
• "Win7"
• "Win8"
• "Win81"
• "Win10"
• "Win11"
• "Haiku"

SYSTEMVERSION (read-only)

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 macOS is system version.

SYSTEMLANGUAGE (read-only)

Returns the user's preferred user interface language as a BCP 47 tag, like "en-US", "pt-BR" or "sr-Latn-RS". Returns NULL when the system has no language, like the "C" locale on Unix. On Linux and BSD it is taken from the LANGUAGE, LC_ALL, LC_MESSAGES or LANG environment variables, the first one that is set.

SYSTEMLOCALE (read-only)

Returns the character encoding used by the C runtime, like "UTF-8". On Windows it is the ANSI code page, like "CP1252", or "UTF-8" when that is the code page.

FONTLIST (read-only)

Returns the names of the font families available in the system, sorted alphabetically. Each name is terminated by a "\n" character.

SCROLLBARSIZE (read-only)

Returns the width of the vertical scrollbar (the same as the height of the horizontal scrollbar).

COMCTL32VER6 (read-only) [Windows Only]

Returns YES or NO if the Windows common controls are using Visual Styles or not.

DARKMODE (read-only)

Returns "YES" when the application is in dark mode, "NO" otherwise. Follows the system setting unless APPEARANCE forces a value.

APPEARANCE

Forces the appearance of the application only, it never changes the system setting. Can be: "SYSTEM" (follow the system setting), "LIGHT" or "DARK". Default: "SYSTEM".

Re-seeds the global palette (DLGBGCOLOR, TXTBGCOLOR, MENUBGCOLOR and their foregrounds), applies the appearance to the native controls and re-applies the palette to every element that did not set its own BGCOLOR or FGCOLOR. Can be set before or after IupOpen. Set it before creating dialogs for a fully consistent result, some native controls pick their theme when they are created.

In Win32 the native file, font and month-calendar dialogs are not affected. In Qt it needs Qt 6.8 or newer for the platform theme, older versions only get the palette. In GTK and GTK 4 it selects the dark variant of the current theme, so a theme without one keeps its colors. In EFL and GNUstep only the IUP palette follows it, the widgets keep the toolkit theme. In Haiku the controls and menus of the IUP dialogs draw with the palette; the native dialogs, tooltips and the window frame keep the system colors.

The dialog THEMECHANGED_CB is called when the appearance changes, whether from a live system switch or from this attribute.

WINDOWING (read-only)

Returns the native windowing system in use. Can be: "DWM", "X11", "WAYLAND", "QUARTZ", "ANDROID", "HAIKU" or "WEB".

Default Attributes

DLGBGCOLOR

The default background color for all elements that have the background similar of the dialog.

DLGFGCOLOR

The default foreground color for all elements that have text over the background of the dialog or similar. Usually is "0 0 0" - black.

MENUBGCOLOR

The default menu background color. Usually is "255 255 255" - white.

MENUFGCOLOR

The system default menu foreground color. Usually is "0 0 0" - black.

TXTBGCOLOR

The default background color for editable text, also used by lists and tree. Usually is "255 255 255" - white.

TXTFGCOLOR

The default foreground color for editable text, also used by lists and tree. Usually is "0 0 0" - black.

TXTHLCOLOR

The default highlight color for editable text, also used by lists and tree. The highlight color is used when the text is selected. Usually is "0 0 0" in Motif, and "51 153 255" in Windows. It can be changed only in IupTree, and only in Windows and Motif. But it can be used for drawing selected areas in custom controls.

LINKFGCOLOR

The default foreground color for linked text. In GTK and Motif is "0 0 238".

ACCENTCOLOR

The system accent color (read-only). This is the user-selected theme accent color used for primary buttons, toggles, progress bars, focus indicators, and similar UI elements. Unlike TXTHLCOLOR (which is the text selection background), this reflects the toolkit's notion of the platform accent.

On some platforms, this value coincides with TXTHLCOLOR because the toolkit derives text selection from the same source.

DEFAULTFONTFACE

Auxiliary attribute to retrieve and set the default font face used by all elements. It retrieves the typeface from DEFAULTFONT. When changed will actually change the DEFAULTFONT.

DEFAULTFONTSIZE

Auxiliary attribute to retrieve and set the default font size used by all elements. It retrieves the size from DEFAULTFONT. When changed will actually change the DEFAULTFONT.

DEFAULTFONTSTYLE

Auxiliary attribute to retrieve and set the default font style used by all elements. It retrieves the style from DEFAULTFONT. When changed will actually change the DEFAULTFONT.

DEFAULTBUTTONPADDING

Default button padding used in pre-defined dialogs. Default: 12x4".

DEFAULTTHEME

Applies a default theme for all controls. See THEME attribute for more information.
