Form Glass Pane in LWUIT - web-services

Question

I'm trying to make a waiting screen using Form Glass Pane in LWUIT, the following is the code that I'm using
public class LoadingGlassPane implements Painter {
public static boolean isShown = false;
public static IForm form;
public void paint(Graphics g, Rectangle rect) {
System.out.println("paint LoadingGlassPane");
Font font = g.getFont();
int color = g.getColor();
g.setColor(0);
g.setFont(Font.getDefaultFont());
g.drawString("Loading...", 20, 120);
g.setColor(color);
g.setFont(font);
}
public void installPane(IForm f) {
f.setGlassPane(this);
}
public void uninstallPane(IForm f) {
f.setGlassPane(null);
}
public static IForm getForm() {
return form;
}
public static void setForm(IForm form) {
LoadingGlassPane.form = form;
}
public static boolean isIsShown() {
return isShown;
}
public static void setIsShown(boolean isShown) {
LoadingGlassPane.isShown = isShown;
}
}
and
public class ProgressGlassPane extends LoadingGlassPane implements Animation, Runnable {
int spacing = 20;
int fontSpacing = 10;
String loadMsg = "Loading...";
//HTMLComponent htmlC;
// Dialog loading;
// public ProgressGlassPane(Dialog loading) {
// this.loading = loading;
// }
public ProgressGlassPane() {
}
public void paint(Graphics g, Rectangle rect) {
//while (isShown == true) {
System.out.println("paint ProgressGlassPane");
int color = g.getColor();
Font font = g.getFont();
int pos = (int) ((System.currentTimeMillis() % 2700) / 300);
Font f = Font.getDefaultFont();
//int startX = loading.getAbsoluteX() + (loading.getWidth() / 2) - spacing;
int startX = (LGB.width / 2) - spacing;
//int fontStartX = loading.getAbsoluteX() + (loading.getWidth() - f.stringWidth(loadMsg)) / 2;
int fontStartX = (LGB.width - f.stringWidth(loadMsg)) / 2;
//int startY = loading.getAbsoluteY() + (loading.getHeight() / 2) - spacing - (f.getHeight() + fontSpacing) / 2;
int startY = (LGB.height / 2) - spacing - (f.getHeight() + fontSpacing) / 2;
int i = 0;
g.setColor(0xffffff);
g.fillRect(Math.min(startX - 3, fontStartX), startY - 3, Math.max(spacing * 2 + 7, f.stringWidth(loadMsg)) + 1, spacing * 2 + 7 + f.getHeight() + fontSpacing);
g.setColor(0);
g.setFont(f);
g.drawString(loadMsg, fontStartX, startY);
startY += f.getHeight() + fontSpacing;
for (int y = 0; y < 3; y++) {
for (int x = 0; x < 3; x++) {
int thickness = 3;
if (i == pos) {
thickness = 7;
} else if (i == pos - 1) {
thickness = 5;
}
g.fillRect(startX + x * spacing - (thickness / 2), startY + y * spacing - (thickness / 2), thickness, thickness);
i++;
}
}
g.setColor(color);
g.setFont(font);
// }
}
public boolean animate() {
return true;
}
public void paint(Graphics g) {
paint(g, null);
}
//void installPane(Form f) {
public void installPane(IForm f) {
super.installPane(f);
//f.setGlassPane(this);
f.registerAnimated(this);
}
//void uninstallPane(Form f) {
public void uninstallPane(IForm f) {
super.uninstallPane(f);
//f.setGlassPane(this);
f.deregisterAnimated(this);
}
public void run() {
System.out.println("I'm running");
if (isShown == true && form != null) {
installPane(form);
}
else
{
uninstallPane(form);
}
}
}
and from within my form
public static ProgressGlassPane progressPane;
progressPane = new ProgressGlassPane();
progressPane.setForm(this);
progressPane.setIsShown(true);
progressPane.run();
//Some Webservice code I want to run
progressPane.setIsShown(false);
What I want to do exactly is to open the glass pan while I'm loading my data and hide it when I finish, but what Happen it send the request and after get the response show the glass pane , I have tried to put my glass pane in different thread to run independently from the main thread, and it is also not working.

Answer 1

Is the webservice code blocking?
If you are on the EDT then that just wouldn't work. You need to uninstall from the completion.
