RadioButton Macro This macro is used to create those swell radio buttons. You typically use this only in command-line mode, as it does some automatic output file naming for you. The first step is to create and specify a directory where you want to place the icons. This is typically $HOME/nreal/icons/ux/radio, as they tend to pile up, but you can place them anywhere. Open the radiobutton.h file and look for the filePath declaration, line 6 below: image RadioButton( const char *text="linear", // lengths are 74, 37, 53 int length = 74, string fileName=text, string filePath="$HOME/nreal/icons/ux/radio/", int branch=time, ... Make sure that directory exists. The standard image lengths are 37, 53, and 74 pixels long. The shortest you can practically do is 19. Finally, it calls on the font Arial. If you do not have this font, search for the word and substitute an appropriate font. The parameters are: • "text": You can type it, or if you want more than one word, enclose it in "quotation marks." • length: Output pixel width. Standard lengths are 37, 53, and 74 pixels. • fileName: "text" by default. The macro appends .on.nri, on.focus.nri, .off.nri, and .off.focus.nri for frames 1, 2, 3, and 4. • filePath: Redirect the output directory without editing the file. • xScale: Scale the text on the X axis if you have to squeeze the letters a bit. The default is 1. • zoom: Creates a button 19 pixels high by default, but you can scale it up. The default value is .25. • branch: Specifies the state you want the macro. Normally you do not have to touch this, you just change the frame number, to which this parameter is set. • 1 = on • 2 = on + focus • 3 = off • 4 = off + focus Chapter 32 The Cookbook 999
