((IcontrolData*)calloc(1, sizeof(IcontrolData)))

IcontrolData allocation utility.

Typedef Documentation

typedef struct _InativeHandle InativeHandle

A simple definition that do not depends on the native system, but helps a lot when writing native code. See iup_object.h for definitions.

typedef struct _IcontrolData IcontrolData

Each control may define its own structure in its private module.

Enumeration Type Documentation

enum Iexpand

Expand configuration

enum Iflags

General flags.

Enumerator:

IUP_FLOATING	is a floating element. FLOATING=Yes
IUP_FLOATING_IGNORE	is a floating element. FLOATING=Ignore. Do not compute layout.
IUP_MAXSIZE	has the MAXSIZE attribute set
IUP_MINSIZE	has the MAXSIZE attribute set
IUP_INTERNAL	it is an internal element of the container

Function Documentation

IUP_SDK_API void** iupObjectGetParamList	(	void *	first,
		va_list	arglist
	)

Utility that returns an array of parameters. Must call free for the returned value after usage. Used by the creation functions of objects that receives a NULL terminated array of parameters.

IUP_SDK_API int iupObjectCheck

(

Ihandle *

ih

)

Checks if the handle is still valid based on the signature. But if the handle was destroyed still can access invalid memory.
