Classes

This file documents the compliance of all the classes in the GNUstep Gui library. Note that the following is just a best guess as to the compliance of the classes. Each class was checked to make sure it implemented all the documented OpenStep methods and functions. In addition, extensive testing has been performed on the GNUstep Gui Library, and it is believed, to the best of our knowledge, that it operates according to the OpenStep specification, with the caveat that there are always bugs in any implementation and there are most likely bugs in the current implementation that we are not aware of.

The following classes conform to the OpenStep specification:

• NSActionCell
• NSBox
• NSBrowser
• NSBrowserCell
• NSBundleAdditions
• NSButton
• NSButtonCell
• NSCachedImageRep
• NSClipView
• NSColor
• NSColorList
• NSColorPanel
• NSColorPicker
• NSColorWell
• NSControl
• NSCursor
• NSCustomImageRep
• NSEvent
• NSFont
• NSFontManager
• NSFontPanel
• NSForm
• NSFormCell
• NSImage
• NSImageRep
• NSMenu
• NSOpenPanel
• NSPanel
• NSPasteboard
• NSPopUpButton
• NSPrintInfo
• NSPrintOperation
• NSResponder
• NSScreen
• NSScroller
• NSSelection
• NSSlider
• NSSliderCell
• NSSpellChecker
• NSSpellServer
• NSSplitView
• NSText
• NSTextField
• NSTextFieldCell
• NSView
• All Protocols

The following classes are only partially implemented

NSApplication

-preventWindowOrdering not implemented. In -activateIgnoringOtherApps:, the flag is ignored.

NSBitmapImageRep

-initWithFocusedViewRect: not implemented in Windows backend. +TIFFRepresentationOfImageRepsInArray:usingCompression:factor: not fully implemented.

NSCell

-setFloatingPointFormat:left:right: not implemented. -setEntryType: not complete.

NSDataLink

Mostly unimplemented.

NSDataLinkManager

Mostly unimplemented.

NSDataLinkPanel

-setAccessoryView:, NSCoding methods not implemented.

NSEPSImageRep

Cannot interpret/draw EPS images

NSMatrix

-setValidateSize: not implemented

NSPageLayout

-setAccessoryView: not implemented. Several methods have been depreciated because they don't do anything useful.

NSPrintPanel

-setAccessoryView: not implemented. Several methods have been depreciated because they don't do anything useful.

NSPrinter

Doesn't really get all the information it needs correctly.

NSSavePanel

NSCoding protocol not implemented.

NSScrollView

-toggleRuler: and -isRulerVisible: not implemented. (Replaced by similar methods).

NSWindow

-resizeFlags not implemented.

NSWorkspace

Many methods require a proper window and workspace manager application to be used.

Functions

Following are not implemented: NSReadPixel, all text functions, NSFrameLinkRect.

The following OpenStep classes are not implemented. These classes are either not very useful or have been replaced by classes with better APIs.

• NSCStringText (Unecessary NEXTSTEP compatibility)
• NSCoderAdditions (Unecessary NEXTSTEP compatibility)
• NSHelpPanel (Replaced by NSHelpManager)
• NSMenuCell (Replaced by NSMenuItem[Cell])
