Typedef Documentation

IlvAlignment

A synonym for IlvPosition.

IlvDirection

A synonym for IlvPosition.

IlvDisplayCallback

This type defines the prototype of the functions used as callbacks when the look or the language are dynamically changed.

Parameters

userArg

The user argument that was provided when the callback was set.

See Also

IlvDisplay::addChangeLookCallback(), IlvDisplay::addChangeLanguageCallback().

IlvDisplayConfigCallback

This type defines the prototype of the function that can be used as a display configuration callback, which is used in the IlvDisplay constructors.

Parameters

config

The display configuration created by the constructor of IlvDisplay.

IlvMarkerType

The different aspects that an IlvMarker can take.

See Also

IlvMarkerSquare, IlvMarkerDiamond, IlvMarkerCircle, IlvMarkerCross, IlvMarkerPlus, IlvMarkerFilledSquare, IlvMarkerFilledCircle, IlvMarkerFilledDiamond, IlvMarkerTriangle, IlvMarkerFilledTriangle.

IlvOrientation

A synonym for IlvPosition.

IlvSystemView

A system-dependent type that holds a window.

• On Windows, you can safely cast an IlvSystemView to a HWND to get the real Windows handle of that view.
• On Unix, you can safely cast an IlvSystemView to a Window to get the real X11 Window identifier.

IlvTransfoParam

The type of the internal values of all IlvTransformers.

The IlvTransformer API is based on the IlvTransfoParam type, which stores floating point data. The manner in which data is stored depends on the machine.

Enumeration Type Documentation

enum IlvLookStyle

Predefined positioning and direction values.

This enum type defines the look and feel used by graphic objects in an IlvDisplay instance. By default, only one style is available in a Rogue Wave Views program, and that is the standard style of the current computer system.
To use more than one style in your program, use the corresponding compiler flag, or add the corresponding style header file directive to your implementation file (before any other #include directive). The header files are ilviews/motif.h, ilviews/windows.h, ilviews/win95.h, ilviews/winxp.h and ilviews/vx.h.

See Also

IlvDisplay::setCurrentLook, IlvDisplay::setLookFeelHandler(), IlvDisplay::getLookFeelHandler(), IlvDisplay::getCurrentLook().

Enumerator
IlvOtherLook	This value is used to describe a user defined look and feel.
IlvMotifLook	The Motif look and feel.
IlvWindowsLook	The Windows 3.1 look and feel.
IlvWindows95Look	The Windows 95 look and feel. This also covers Windows 98, Windows NT 4.0, and Windows 2000.
IlvWindowsXPLook	The Windows XP look and feel. This look is available only on machines running Windows XP.
IlvVXLook	The ViewsX look and feel.

enum IlvPosition

Predefined positioning and direction values.

A set of useful terms that are associated with the IlvPosition enumeration type is defined. IlvDirection is a synonym for this same enum type, as these values can be used in a positioning context as well as in a direction context.

See Also

IlvDirection.

Enumerator
IlvBadPosition	An invalid position or direction.
IlvLeft	The left position or direction.
IlvRight	The right position or direction.
IlvTop	The top position or the upwards direction.
IlvBottom	The bottom position or the downwards direction.
IlvTopLeft	The top-left position or direction.
IlvBottomLeft	The bottom-left position or direction.
IlvTopRight	The top-right position or direction.
IlvBottomRight	The bottom-right position or direction.
IlvCenter	The center position or direction.
IlvHorizontalCenter	The horizontal direction, used in alignment.
IlvVerticalCenter	The vertical direction, used in alignment.
IlvHorizontal	The horizontal direction, used in alignment.
IlvVertical	The vertical direction, used in alignment.

Function Documentation

void IlvFatalError	(	const char *	format,
			...
	)

Outputs an error message.

This function calls the fatal member function of the error handler that is installed, if there is one.
The default behavior outputs the message on the standard output stream (or the output TTY on Windows).

Parameters

format

A formatting string that is interpreted as the regular C function printf. This function expects its parameters in the same way as printf does (function with a variable number of arguments).

See Also

IlvError, IlvWarning, IlvPrint, IlvGetErrorHandler, IlvSetErrorHandler.

const char* IlvGetDefaultHome

(

)

Retrieves the default Rogue Wave Views Home directory.

This function allows you to check the setting of ILVHOME, which is used as the base directory of many default resource files.

Returns

The current setting of the default ILVHOME value. For Rogue Wave Views <X.Y>, the default value is "C:\Program Files\Rogue Wave\Views X.Y" on Windows systems, and "/usr/local/roguewave/viewsXY" on Unix systems.

See Also

IlvSetDefaultHome().

const char* IlvGetMessage	(	IlvDisplay *	display,
		const char *	label
	)

Alias for IlvDisplay::getMessage()

Parameters

display	The display.
label	The message identifier.

See Also

IlvDisplay::getMessage().

IlvPosition IlvPositionFromString

(

const char *

position

)

Converts a string value to an IlvPosition.

Parameters

position

The string you want to convert.

Returns

The IlvPosition enum value whose symbol equals position, even if position does not have the 'Ilv' prefix.
If position is 0 or matches none of the IlvPosition values, this function returns IlvBadPosition.

void IlvPrint	(	const char *	format,
			...
	)

Outputs a message.

This function outputs the message on the standard output stream (or the output TTY on Windows).

Parameters

format

A formatting string that is interpreted as the regular C function printf. This function expects its parameters in the same way as printf does (function with a variable number of arguments).

See Also

IlvFatalError, IlvWarning.

void IlvSetDefaultHome

(

const char *

defaultHome

)

Sets the default Rogue Wave Views Home directory.

This global function sets the setting of the default ILVHOME value to a copy of the string defaultHome.
You may want to force this setting if you want to provide a reasonable default value for a specific application without requesting the user to set the environment variable ILVHOME or the display resource Home.

Parameters

defaultHome

The new default Home setting.

See Also

IlvGetDefaultHome.

IlvLocaleExtension* IlvSetLocale

(

const char *

locale = 0

)

Sets the language of the application according to the locale environment.

IlvSetLocale() must be called before creating an instance of IlvDisplay. The implementation of this function is platform dependent but is usually carried out by calling setlocale(LC_ALL, "");

Please check the User's Manual for a list of supported locales.

Parameters

locale

A platform dependent string specifying the locale. If 0, the default user locale is used.

Returns

A pointer to an internal class. If success, the returned value is not 0.

const char* IlvToString

(

IlvPosition

position

)

Converts an IlvPosition to a string value.

Parameters

position

The value you want to convert.

Returns

A string representation of position. It returns a string that is the same as the enum value, with the prefix 'Ilv' removed.
"UnknownPosition" is return if position is unknown enum value.
Note that IlvHorizontalCenter is converted to "Horizontal" and IlvVerticalCenter is converted to "Vertical".
The return string must not be deleted.

void IlvWarning	(	const char *	format,
			...
	)

Outputs a warning message.

This function calls the warning member function of the error handler that is installed, if there is one.
The default behavior outputs the message on the standard output stream (or the output TTY on Windows).

Parameters

format

A formatting string that is interpreted as the regular C function printf. This function expects its parameters in the same way as printf does (function with a variable number of arguments).
