I am trying to use naive map.
I have places a MapContainer insider a Form Component but the From shows blank without the map inside it, on the simulator. When I click on the viewport the map shows as long as the mouse button remains down. When I release it disappear again.
Is it a real problem or is it a misfunction of the simulator? If it is a real problem what am I doing wrong?
below is the class I am using:
package com.mainsys.zappeion;
import com.codename1.googlemaps.MapContainer;
import com.codename1.maps.Coord;
import com.codename1.ui.Form;
import com.codename1.ui.layouts.BorderLayout;
/**

*/
public class ZappeionMap extends com.codename1.ui.Form {
private Form current;
public ZappeionMap() {
super("Ζάππειον", new BorderLayout());
}
#Override
public void show() {
if(current != null){
current.show();
return;
}
final MapContainer cnt = new MapContainer();
this.addComponent(BorderLayout.CENTER, cnt);
cnt.setCameraPosition(new Coord(41.889, -87.622));
super.show();
}
}
/********** Implementing Shai's answer ******************/
I changed my code to what Shai suggested show my class now is:
package com.mainsys.zappeion;
import com.codename1.googlemaps.MapContainer;
import com.codename1.location.Location;
import com.codename1.location.LocationManager;
import com.codename1.maps.Coord;
import com.codename1.ui.BrowserComponent;
import com.codename1.ui.FontImage;
import com.codename1.ui.Form;
import com.codename1.ui.layouts.BorderLayout;
import com.codename1.ui.plaf.Style;
/**

public class ZappeionMap extends com.codename1.ui.Form {
private Form current;
private static final String HTML_API_KEY = "AIzaSyDHlFJK561bQVs0AyBm1M5xWS_YCHNuPfc";
public ZappeionMap() {
super("Ζάππειον", new BorderLayout());
final MapContainer cnt = new MapContainer( HTML_API_KEY );
this.addComponent(BorderLayout.CENTER, cnt);
cnt.setCameraPosition(new Coord(41.889, -87.622));
}
}
It still having the same problem. The screen is blank. The map only shown when I click on the screen.
I also noticed something else. On the debuger I get the message:
WARNING: Apple will no longer accept http URL connections from applications you tried to connect to http://tile.openstreetmap.org/4/2/9.png to learn more check out https://www.codenameone.com/blog/ios-http-urls.html
Why is it trying to connect to http://tile.openstreetmao.org. It is supposed to work with google maps not with openstreet maps.
One more information, maybe it is worh something. I test it on real device. The screen is still blink but when I touch the screen it does not show anythink, in contrast with the simulater that when I click on the screen the map appears.
I am using netbeans 8.2 on centos 7
Any help is appreciated.
Thank you Christoforos.
Why are you overriding the show method of form and don't construct the UI n the constructor?
It looks like you copied some code from the lifecycle class and mixed it with a form subclass e.g. the current variable.
This is closer to correct:
public class ZappeionMap extends com.codename1.ui.Form {
private Form current;
public ZappeionMap() {
super("Ζάππειον", new BorderLayout());
final MapContainer cnt = new MapContainer();
this.addComponent(BorderLayout.CENTER, cnt);
cnt.setCameraPosition(new Coord(41.889, -87.622));
}
}
I hand-coded my app using CN1 (based on CN1's standard form template). Mostly for using Calendar for appointment app (I have reason not to use Picker).
Here's my main Form class
public class celebriesta {
private Form current;
private Resources theme;
private Form home;
public void init(Object context) {
theme = UIManager.initFirstTheme("/theme");
// Enable Toolbar on all Forms by default
Toolbar.setGlobalToolbar(true);
// Pro only feature
Log.bindCrashProtection(true);
}
public void start() {
if (current != null) {
current.show();
return;
}
home = new Form("Home", BoxLayout.y());
mainCalendar Calendar = new mainCalendar();
home.addComponent(Calendar);
Calendar.setUIID("Calendar");
//Create Form1 and Form2 and set a Back Command to navigate back to the home Form
Form form1 = new Form("Form1");
setBackCommand(form1);
Form form2 = new Form("Form2");
setBackCommand(form2);
Form form3 = new Form("Form3");
setBackCommand(form3);
//Add navigation commands to the home Form
NavigationCommand cmd1 = new NavigationCommand("Form1");
cmd1.setNextForm(form1);
home.getToolbar().addCommandToSideMenu(cmd1);
NavigationCommand cmd2 = new NavigationCommand("Form2");
cmd2.setNextForm(form2);
home.getToolbar().addCommandToSideMenu(cmd2);
NavigationCommand cmd3 = new NavigationCommand("Form3");
cmd3.setNextForm(form3);
Calendar.createDay().pressed();
Calendar.createDay().released();
Calendar.createDay().setCommand(cmd3);
//Add Edit commands to the home Form context Menu
Image im = FontImage.createMaterial(FontImage.MATERIAL_MODE_EDIT, UIManager.getInstance().getComponentStyle("Command"));
Command edit = new Command("", im) {
#Override
public void actionPerformed(ActionEvent evt) {
System.out.println("Editing");
}
};
home.getToolbar().addCommandToRightBar(edit);
home.show();
}
protected void setBackCommand(Form f) {
Command back = new Command("") {
#Override
public void actionPerformed(ActionEvent evt) {
home.showBack();
}
};
Image img = FontImage.createMaterial(FontImage.MATERIAL_ARROW_BACK, UIManager.getInstance().getComponentStyle("TitleCommand"));
back.setIcon(img);
f.getToolbar().addCommandToLeftBar(back);
f.getToolbar().setTitleCentered(true);
f.setBackCommand(back);
}
public void stop() {
current = getCurrentForm();
}
public void destroy() {
}}
I've override Calendar class accordingly
public class mainCalendar extends Calendar { #Override
protected Button createDay(){ Button day = new Button();
Image im = FontImage.createMaterial(FontImage.MATERIAL_MODE_EDIT, UIManager.getInstance().getComponentStyle("Command"));
day.setIcon(im);
return day;
}
#Override
protected void updateButtonDayDate(Button dayButton, int currentMonth, int day) {
//Customize day values
dayButton.setText("" +day);
}}
The main Form manages to get to Form 1 & 2 (sidemenu). I know Form 3 does exist but not sure why it didn't managed to be 'reached' from createDay(). And I suspect it's something wrong somewhere around this code in main Form
Calendar.createDay().pressed();
Calendar.createDay().released();
Calendar.createDay().setCommand(cmd3);
Need advise and/or help.
Have a look at a sample code here that creates a custom calendar day component. You don't need the below code:
Calendar.createDay().pressed();
Calendar.createDay().released();
Calendar.createDay().setCommand(cmd3);
Calendar day pressing and releasing is handled through an actionListener which you can implement through overriding the bindDayListener() if you're using a custom day component or addDayActionListener() if you're using the default day button. An example will be:
Calendar.addDayActionListener(evt -> {
//show your next form here
});
Unless you need a high-level customization, I don't see a point subclassing the Calendar class.
I'm beginner in JavaFX.
I need to make one-at-a-time handler for any changes in the check boxes for my TreeView. Now it works like it handles all selected nodes simultaneously.
Thanks for help. Here is my code:
package sample;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.CheckBoxTreeItem;
import javafx.scene.control.TreeView;
import javafx.scene.control.cell.CheckBoxTreeCell;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
public class Main extends Application {
#Override
public void start(Stage primaryStage) throws Exception{
BorderPane root = new BorderPane();
root.setCenter(initTreeView());
primaryStage.setTitle("Hello World");
primaryStage.setScene(new Scene(root, 300, 275));
primaryStage.show();
}
public TreeView initTreeView() {
TreeView<String> treeView = new TreeView<>();
treeView.setRoot(new CheckBoxTreeItem<>("123"));
treeView.getRoot().addEventHandler(CheckBoxTreeItem.checkBoxSelectionChangedEvent(), event -> System.out.println("hello"));
treeView.setCellFactory(p -> new CheckBoxTreeCell<>());
treeView.getRoot().getChildren().addAll(new CheckBoxTreeItem<>("1"),new CheckBoxTreeItem<>("2"), new CheckBoxTreeItem<>("3"));
treeView.getRoot().getChildren().get(0).getChildren().addAll(new CheckBoxTreeItem<>("4"),new CheckBoxTreeItem<>("5"), new CheckBoxTreeItem<>("6"));
treeView.getRoot().getChildren().get(1).getChildren().addAll(new CheckBoxTreeItem<>("7"),new CheckBoxTreeItem<>("8"), new CheckBoxTreeItem<>("9"));
treeView.getRoot().getChildren().get(2).getChildren().addAll(new CheckBoxTreeItem<>("10"),new CheckBoxTreeItem<>("11"), new CheckBoxTreeItem<>("12"));
return treeView;
}
public static void main(String[] args) {
launch(args);
}
}
Actually it works correctly. Your event handler is called once for every changed checkbox node. Just note that changing subnodes affects parent ones as well, so you get several event handles calls.
Try next code instead which prints the name of the affected checkbox:
treeView.getRoot().addEventHandler(CheckBoxTreeItem.checkBoxSelectionChangedEvent(),
event -> System.out.println("hello " + event.getTreeItem().getValue()));
For example, if you click on checkbox "5" you will get the following log:
hello 5
hello 1
hello 123
because all parent node have changed state as well (from unchecked to intermediate "-" state). If you click "6" after that only one checkbox is affected and output will be:
hello 6
i want to implement an application where i should be able to login as a subscriber and i should be able to see the messages/data coming from publisher which am subscribed to.then i should be able to unsubscribe and subscribe to other publishers if i want to.
using JMS,ActiveMQ,SpringBoot i have created a sample standalone application but from here how to connect and communicate to my web application back and forth.
Here is my implemented standalone application code
application.properties
spring.jms.pub-sub-domain=true

// TODO Auto-generated method stub
Thread.sleep(5000); // wait for subscriptions, unless they are durable
this.jmsTemplate.convertAndSend(this.topic1,"-----> 1st message from publisher -- topic 1");
Thread.sleep(5000);

I stuck at point i have one website for example (http://newtours.demoaut.com/) and for that i have created multiple classes likes:
App_Login(),
App_Dashboard(),
App_FliReservation(),
Cancel_Flight();
So want to call above all classes into single class .
can someone guide me on these.
Script sample
App_Login() class
public class App_login {
public static void main(String[] args) {
// TODO Auto-generated method stub
WebDriver driver= new FirefoxDriver();
driver.get("http://newtours.demoaut.com/");
}
}
and i want to call above class into following class
public class Mercurywebapp {
#Test
public void supp_onboarding() throws Exception {
App_Login();
}
public void App_Login() {
// TODO Auto-generated method stub
}
}
when i run above class (i.e.Mercurywebapp) then getting blank screen
Create another instances of all the Classes in the MercuryWebapp
Depends on the access modifiers for the classes
e.g
App_Login testObject = new App_Login();
