nuiPopControlGroup(); nuiPushControlWidget( "MyFunction.Color", nuiConnectColorPControl( kRGBToggle, kCurrentColor, 1 ) ); This is an older version of the Color control without the cool extra controls. Changing Default Values In the /include/nrui.h file: nuiPushToolBox("Color"); nuiToolBoxItem("Add", Add(0,0,0,0,0,0)); nuiToolBoxItem("AdjustHSV", AdjustHSV(0)); nuiToolBoxItem("Brightness", Brightness(0,1)); nuiToolBoxItem("Clamp", Clamp(0)); nuiToolBoxItem("ColorCorrect", ColorCorrect(0)); ... In the include/nreal.h file, most functions have their default values declared, but not all of them. To override the default values when you call the function, modify the line that loads the function in the interface. If every parameter in a function has a default value in a function, you can call the function with something like: nuiToolBoxItem("Clamp", Clamp(0)); Normally, Clamp has about 8 values. Here, the 0 represents in the first argument, the input image. 0 is used to indicate that no images are expected to be inserted, so you can attach it to the active node. However, you can add additional parameters. For example, the Brightness line above it has (0,1), 0 for the image input (no input) and 1 for the brightness value. Change the 1 to a different value to override it. You only need to supply the parameters up to the one you want. For example, the following is the call for the Text function: nuiToolBoxItem("Text", Text()); To override the default font for the Text function, you have to supply the width, height, bytes, text, and finally the font. The rest you can ignore afterward: nuiToolBoxItem("Text", Text( GetDefaultWidth(), GetDefaultHeight(), GetDefaultBytes(), "Yadda Yadda", "Courier" ) ); Chapter 14 Customizing Shake 381
