e747. Moving the Icon in a JButton ComponentThere are two methods for controlling the position of the text relative to the icon - -setVerticalTextPosition() and
setHorizontalTextPosition() . There are three settings for each
axis, which allows for a total of nine positions.
To control the gap between the text and icon, see e749 Setting the Gap Size Between the Label and Icon in a JButton Component. Note: Not all placements are possible. For example, it is not possible to place the text above the icon with their left edges aligned. The nine possible placements are demonstrated below. // To create a button with an icon, see e746 Adding an Icon to a JButton Component // Place text over center of icon; they both occupy the same space button.setVerticalTextPosition(SwingConstants.CENTER); button.setHorizontalTextPosition(SwingConstants.CENTER); // Place text above icon button.setVerticalTextPosition(SwingConstants.TOP); button.setHorizontalTextPosition(SwingConstants.CENTER); // Place text below icon button.setVerticalTextPosition(SwingConstants.BOTTOM); button.setHorizontalTextPosition(SwingConstants.CENTER); // Place text to the left of icon, vertically centered button.setVerticalTextPosition(SwingConstants.CENTER); button.setHorizontalTextPosition(SwingConstants.LEFT); // Place text to the left of icon and align their tops button.setVerticalTextPosition(SwingConstants.TOP); button.setHorizontalTextPosition(SwingConstants.LEFT); // Place text to the left of icon and align their bottoms button.setVerticalTextPosition(SwingConstants.BOTTOM); button.setHorizontalTextPosition(SwingConstants.LEFT); // Place text to the right of icon, vertically centered button.setVerticalTextPosition(SwingConstants.CENTER); button.setHorizontalTextPosition(SwingConstants.RIGHT); // Place text to the right of icon and align their tops button.setVerticalTextPosition(SwingConstants.TOP); button.setHorizontalTextPosition(SwingConstants.RIGHT); // Place text to the right of icon and align their bottoms button.setVerticalTextPosition(SwingConstants.BOTTOM); button.setHorizontalTextPosition(SwingConstants.RIGHT);
