The Button Layout Tab Buttons Layout and Applet Size Specifies how the buttons are arranged.   There are three options: Vertical Column of Buttons.   Buttons are arranged in a column, the first button at the top.   Each button is the Default Size and spaced accoring to the Horizontal and Vertical Spacing settings. Horizontal Row of Buttons.   Buttons are arranged in a row, the first button at the left.   Each button is the Default Size and spaced accoring to the Horizontal and Vertical Spacing settings. Specify Size and Position of Each Button.   Lets you arrange buttons however you like!   You can move and resize buttons by using the handles on the The Button Editor Window.   You can also set the total applet size by resizing the Button Editor Window, or typing a size into the Applet Size dialog box. Button Size and Spacing Default Button Size.   If your buttons are arranged in a column or row, all buttons will be this size. Also, buttons created by pressing New Text Button (on the The Main Toolbar) will default to this size. Horizontal Spacing.   The number of pixels to the left and right of each button in a row of buttons.   This also specifies the width of the border around a row or column of buttons.   It has no effect if you are specifying the position of each button Vertical Spacing.   The number of pixels above and below each button in a column of buttons.   This also specifies the height of the border around a row or column of buttons.   It has no effect if you are specifying the position of each button Applet Background The applet background may be either colored or a bitmap. Clicking on the Background Color swatch will display the Color Dialog where you can select a color or enter the RGB values of a color. The only bitmap formats supported by Java are Compuserve GIF, and JPEG.   You can either type a bitmap name into the edit box, or click on the "..." button to open the File Dialog Box. Background bitmaps can be used for interactive image maps, where the up state of the buttons is transparent, and buttons appear only when you move the mouse over them. A background bitmap can be displayed in one of three ways: Tile background bitmap.   The background bitmap is tiled horizontally and vertically across the applet area.   This is ideal for background textures and transparent textured buttons. Scale background to fit applet.   The background bitmap is enlarged or reduced to fit the applet area.   Center background bitmap.   The background bitmap is centered to the applet area.
