| Conforms To: | NXColorPickingDefault | |
| Declared In: | appkit/NXColorPicker.h |
| Class Description |
| NXColorPicker is an abstract superclass that implements the NXColorPickingDefault protocol. The NXColorPickingDefault and NXColorPickingCustom protocols define a way to add color pickers--custom user interfaces for color selection--to the NXColorPanel. The simplest way to implement a color picker is to create a subclass of NXColorPicker that implements the NXColorPickingCustom protocol.
The NXColorPickingDefault protocol specification describes the details of implementing a color picker and adding it to your application's NXColorPanel; you should turn there first for an overview of how NXColorPicker works. This specification is provided to document the specific behavior of NXColorPicker's methods. |
| Adopted Protocols |
| NXColorPickingDefault | initFromPickerMask:withColorPanel: |
| provideNewButtonImage insertNewButtonImage:in: viewSizeChanged: alphaControlAddedOrRemoved: insertionOrder attachColorList: detachColorList: updateColorList: setMode: |
| Instance Variables |
| id imageObject
NXColorPanel *colorPanel BOOL continuous |
| imageObject | Object providing the ButtonCell image | |
| colorPanel | Panel in which the color picker is installed | |
| continuous | YES if color picker updates current color continuously |
| Instance Methods |
| alphaControlAddedOrRemoved: |
| alphaControlAddedOrRemoved:sender |
| Does nothing and returns self. |
| attachColorList: |
| attachColorList:colorList |
| Does nothing and returns self. |
| detachColorList: |
| detachColorList:colorList |
| Does nothing and returns self. |
| insertionOrder |
| (float)insertionOrder |
| Returns 0.4, a value that places NXColorPicker's ButtonCell first in the Matrix from which the user selects color pickers.
See also: |
| insertNewButtonImage:in: |
| insertNewButtonImage:newImage in:newButtonCell |
| Sets newImage as newButtonCell's image by invoking ButtonCell's setImage: method. Returns self. |
| initFromPickerMask:withColorPanel: |
| initFromPickerMask:(int)theMask withColorPanel:thePanel |
| Sets the color picker's color panel to thePanel and returns self. Override this method to respond to the values in theMask or do other custom initialization. If you override this method in a subclass, you should forward the message to super as part of the implementation. |
| provideNewButtonImage |
| provideNewButtonImage |
| Returns the NXImage that represents the NXColorPicker in the NXColorPanel's Matrix of ButtonCells. This method attempts to load the image from a file named MyPickerClass.tiff (where MyPickerClass is the name of your subclass of NXColorPicker) in the MyPickerClass bundle of the application's ColorPicker directory. See "Color Picker Bundles" in the NXColorPickingDefault protocol specification for a more complete discussion of this bundle. |
| setMode: |
| setMode:(int)mode |
| Does nothing and returns self. Override this method if your color picker has submodes to set the mode of the color picker to mode. |
| updateColorList: |
| updateColorList:colorList |
| Does nothing and returns self. |
| viewSizeChanged: |
| viewSizeChanged:sender |
| Does nothing and returns self. |
