Had the same experience at the begining, try this:
In your subclass of Applet initialize the parent window with this in the
start() method:
class ProjectApplet extends Applet {
public Frame projectFrame;
public void init() {
resize(0,0);
}
public void start() {
Window win;
while (((win = item.parent) == null) &&
((item.getStatus() == AppletDisplayItem.STARTED) ||
(item.getStatus() == AppletDisplayItem.INITIALIZING))) {
}
projectFrame = new ProjectFrame(w.wServer, false, null, 380,
200, Color.lightGray);
}
}
Then I wrote a subclass of Frame like:
class ProjectFrame extends Frame {
ProjectWindow win;
ProjectFrame(WServer ws, boolean hasTitleBar, Frame parentFrame, int
w, int h, Color bg) {
super(ws, hasTitleBar, parentFrame, w, h, bg);
super.setTitle("Projects");
super.setMinSize(width+20, height+100);
win = new ProjectWindow(this, "Center", bg, width, height+100);
map();
}
}
And finally you'll need your own version of a window:
class ProjectWindow extends Window implements ChoiceHandler {
public List list;
Label labelProject;
ProjectWindow(Container w, String name, Color bg, int wd, int ht) {
super(w, name, bg, wd, ht);
Row row = new Row(this, null, true);
labelProject = new Label("Projects", "labelProjects", this);
list = new List(this, this, "ProjectList", 10, false, false);
list.select(0);
}
public void selected(Component c, int pos) {
if (c.name == "ProjectList") {
// do whatever you want with it
}
}
public void handleResize() {
labelProject.move(10, 10);
list.reshape(10, 30, width/2 - 20, height-30);
}
}
These are the basic tricks, I only noted the important part of it, you also
have to implement doubleClick() within window because of the choiceHandler
keyword. Note that you can do your own stuff in handleResize() when the window
is resized. handleResize() is an overwritten method of Window.
