Examples with Component java.awt.Component used on opensource projects

Example 1 with Component

use of java.awt.Component in project hackpad by dropbox.

the class RunProxy method updateToolTip.

/**
     * Updates the tool tip contents.
     */
private void updateToolTip() {
    // Try to set tool tip on frame. On Mac OS X 10.5,
    // the number of components is different, so try to be safe.
    int n = getComponentCount() - 1;
    if (n > 1) {
        n = 1;
    } else if (n < 0) {
        return;
    }
    Component c = getComponent(n);
    // this will work at least for Metal L&F
    if (c != null && c instanceof JComponent) {
        ((JComponent) c).setToolTipText(getUrl());
    }
}
