How do I add an Infinite progress till the WebPage is fully loaded?
Form hi = new Form("Hi World");
hi.setLayout(new BorderLayout());
final BrowserComponent wb = new BrowserComponent();
hi.addComponent(BorderLayout.CENTER, wb);
final Dialog ipDlg = new InfiniteProgress().showInifiniteBlocking();
wb.setURL("https://www.codenameone.com");
wb.addWebEventListener("onLoad", new ActionListener() {
#Override
public void actionPerformed(ActionEvent evt) {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
});
hi.show();
ipDlg.dispose();
above is the code I am using.
This won't work since dialog is literally a separate Form. So the browser component will never load and won't show what's going on below.
You can use an InteractionDialog which is just a Container in the layered pane. This means the browser will keep loading and you can draw on top of it. Just add the InfiniteProgress into the InteractionDialog and show it.

I'm building a nokia s40 app. I've set this app to be in full screen mode and I notice that when I set this full screen mode, I've lost the native back buttons.
I need to build a back button like the native back button (always on screen, in the bottom right side of the screen). I've tried it with a borderlayout and putting it on the south, but the text from the center container doesn't appears over this...and has transparent background.
If anyone has some sample code, it will be great.
this code simply located a button in the bottom right side of the screen. it's work well.
public void startApp() {
Display.init(this);
Form f = new Form();
//Create a ComponentGroup for all components except backbutton
final ComponentGroup cg = new ComponentGroup();
final Button backButton = new Button("BackButton");
// add this part to your code
f.addOrientationListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
Dimension d = new Dimension(Display.getInstance().getDisplayWidth(), Display.getInstance().getDisplayHeight());
cg.setPreferredSize(d);
backButton.setX(Display.getInstance().getDisplayWidth() - backButton.getPreferredW());
}
});
//set CoordinateLayout to f
f.setLayout(new CoordinateLayout(Display.getInstance().getDisplayWidth(), Display.getInstance().getDisplayHeight()));
//Dimension d = new Dimension(Display.getInstance().getDisplayWidth(), Display.getInstance().getDisplayHeight());
cg.setPreferredH(Display.getInstance().getDisplayHeight());
cg.setPreferredW(Display.getInstance().getDisplayWidth());
cg.setLayout(new BorderLayout());
cg.addComponent(BorderLayout.NORTH, new Button("NORTH"));
cg.addComponent(BorderLayout.EAST, new Button("ESET"));
cg.addComponent(BorderLayout.WEST, new Button("WEST"));
cg.addComponent(BorderLayout.CENTER, new TextArea("sdsdsd"));
cg.setX(0);
cg.setY(0);
backButton.getStyle().setBgColor(0x2233ff);
backButton.setX(Display.getInstance().getDisplayWidth() - backButton.getPreferredW());
backButton.setY(Display.getInstance().getDisplayHeight() - backButton.getPreferredH() - f.getTitleArea().getLayoutHeight());
f.addComponent(cg);
f.addComponent(backButton);
f.show();
}
you can do like this to any form.
if you want back Button is showed in all forms you can write some OOP programming to do this.
it works well.
I recently started creating an app for blackberry. I want the app to display a screen (Let's say it's called "InfoScreen") but as I said i am still very new to this. What code will I have to use if I want the "InfoScreen" to be show when the button "buttonInfo" is clicked?
Here is some code I used to create the button that is might relevant to this question.
//Create button
ButtonField buttonInfo = new ButtonField("Information", Field.FIELD_HCENTER);
//Center buttons
VerticalFieldManager vfm = new VerticalFieldManager(Field.USE_ALL_WIDTH);
vfm.add(buttonInfo);
add(vfm);
What code will have to be used for both touch-screen devices and those that use the track-pad?
Thanks
Try this:
FieldChangeListener infoListener = new FieldChangeListener() {
public void fieldChanged(Field field, int context) {
UiApplication.getUiApplication().pushScreen(new InfoScreen());
}
};
buttonInfo.setChangeListener(infoListener);
I want to develop a multiple scenes Java FX application. But I want to have the common menu across all scenes. I think using FXML I can create a menu in a scene. But Can I have the same menu across all the scenes even after I navigated to other screen?
If so how is it. Else let me know any alternative for it.
Yes this is possible. I'm using this mechanism in my own application.
What I do first is make an FXML with the menu bar and an AnchorPane who contains the content. This FXML is loaded when the application starts.
I use a Context class (based on the answer of Sergey in this question: Multiple FXML with Controllers, share object) which contains a method ShowContentPane(String url) method:
public void showContentPane(String sURL){
try {
getContentPane().getChildren().clear();
URL url = getClass().getResource(sURL);
//this method returns the AnchorPane pContent
AnchorPane n = (AnchorPane) FXMLLoader.load(url, ResourceBundle.getBundle("src.bundles.bundle", getLocale()));
AnchorPane.setTopAnchor(n, 0.0);
AnchorPane.setBottomAnchor(n, 0.0);
AnchorPane.setLeftAnchor(n, 0.0);
AnchorPane.setRightAnchor(n, 0.0);
getContentPane().getChildren().add(n);
} catch (Exception ex) {
System.out.println(ex.getMessage());
}
}
So what basically happens is:
When the program starts, set content pane in the Context:
#Override
public void initialize(URL url, ResourceBundle rb) {
Context.getInstance().setContentPane(pContent); //pContent is the name of the AnchorPane containing the content
...
}
When a button or menuitem is chosen, I load the FXML in the content Pane:
#FXML
private void handle_FarmerListButton(ActionEvent event) {
Context.getInstance().showContentPane("/GUI/user/ListUser.fxml");
}
Hope this helps :)
I am working on a game where I am extending the view and performing operations in the class. I need to have a popup in the game which will have 3 buttons inside it. I have managed to have the popup show-up using custom dialogs but when I configure the onClick as follows:
private void popUp() {
Context mContext = getContext();
Dialog dialog = new Dialog(mContext);
dialog.setContentView(R.layout.custom_fullimage_dialog);
dialog.setTitle("Cheese Market");
Button one = (Button)findViewById(R.id.firstpack);
one.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
cheeseLeft = cheeseLeft + 10;
masterMoveLock = false;
return;
}
});
}
It force closes giving a nullpointerexeption even though it is defined in the custom_fullimage_dialog layout.
Can someone help me figure out how to have the button click detected in this scenario?
Thank you.
Try calling dialog.findViewById instead.
You're setting the contentView for the dialog, but by calling findViewById you're looking for it under your activity's content view.
I developed an outlook add in (custom task pane), with web browser in the user control.
All the things working well beside the backspace or the delete button when I am writing something in text box in the web browser, I can't use those keys, am I missing something?
I am a few years late to the party but I managed to fix this. The easiest way to fix this is to ensure proper focus is given to the input fields, so you will need to be able to run your own javascript on whatever page is being loaded.
The javascript I run on the page is as follows (using jQuery):
$(document).on("click", function (e) {
// first let the add-in give focus to our CustomTaskPane
window.external.focus();
// then in our web browser give focus to whatever element was clicked on
$(e.target).focus();
});
the window.external variable contains code run from the plugin (c# or VB I assume) which is exposed so we can interact from web page back to the add-in.
In the add-in code for the custom taskpane set the context of window.external:
// event when webBrowser is finished loading document
private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
// sets context of window.external to functions defined on this context
webBrowser1.ObjectForScripting = this;
}
And a public method for focusing:
// can be called by the web browser as window.external.focus()
public void focus()
{
this.Focus();
}
This worked for me, and I hope it helps others. Although do note that this probably doesn't work if the user keyboard navigates using tab, but you can either extend this code for that use case, or safely assume that the average outlook user will have his hand glued to the mouse.
Ok I solved the problem ,
The problem is that the custom task pane in not always gets fucos from the outlook.
So, I raised an event every time that there is "onclick" for all the pane, and then forced the pane to be in focus.
spent a lot of time trying to get this working in Outlook v16.0.13801.20288 the above did not work for me. I ended up with this working code.
Create a user control and add your webbrowser control to it then customize the .cs as below
private void CreateTaskPane() {
MyWinFormUserControl webBrowser = new MyWinFormUserControl();
webBrowser.webBrowser3.Url = new Uri("https://google.com");
webBrowser.webBrowser3.Width = 500;
webBrowser.webBrowser3.Dock = DockStyle.Fill;
webBrowser.webBrowser3.Visible = true;
webBrowser.Width = 500;
webBrowser.Dock = DockStyle.Fill;
webBrowser.Visible = true;
this.CRMTaskPaneControl = CustomTaskPanes.Add(webBrowser, "My App");
//Components.WebViewContainerWPFUserControl webView = (Components.WebViewContainerWPFUserControl)_eh.Child;
//webView.webview.Source = new Uri("https://localhost:3000");
this.CRMTaskPaneControl.Width = 500;
System.Windows.Forms.Application.DoEvents();
this.CRMTaskPaneControl.Control.Focus();
this.CRMTaskPane.Visible = true;
}
public partial class MyWinFormUserControl : UserControl
{
public WebBrowser webBrowser3;
public System.Windows.Forms.WebBrowser webBrowser1;
public MyWinFormUserControl()
{
InitializeComponent();
}
private void InitializeComponent()
{
this.webBrowser3 = new System.Windows.Forms.WebBrowser();
this.SuspendLayout();
//
// webBrowser3
//
this.webBrowser3.Dock = System.Windows.Forms.DockStyle.Fill;
this.webBrowser3.Location = new System.Drawing.Point(0, 0);
this.webBrowser3.MinimumSize = new System.Drawing.Size(20, 20);
this.webBrowser3.Name = "webBrowser3";
this.webBrowser3.Size = new System.Drawing.Size(500, 749);
this.webBrowser3.TabIndex = 0;
this.webBrowser3.DocumentCompleted += new System.Windows.Forms.WebBrowserDocumentCompletedEventHandler(this.webBrowser3_DocumentCompleted);
//
// MyWinFormUserControl
//
this.Controls.Add(this.webBrowser3);
this.Name = "MyWinFormUserControl";
this.Size = new System.Drawing.Size(500, 749);
this.Load += new System.EventHandler(this.MyWinFormUserControl_Load);
this.ResumeLayout(false);
}
void webBrowser3_DocumentCompleted(object sender, System.Windows.Forms.WebBrowserDocumentCompletedEventArgs e)
{
HtmlDocument doc;
doc = webBrowser3.Document;
doc.Click += doc_Click;
}
void doc_Click(object sender, HtmlElementEventArgs e)
{
this.Focus(); // force user control to have the focus
HtmlElement elem = webBrowser3.Document.GetElementFromPoint(e.ClientMousePosition);
elem.Focus(); // then let the clicked control to have focus
}
private void MyWinFormUserControl_Load(object sender, EventArgs e)
{
//Control loaded
}
Turns out this is an easy issue to fix.
Just write
class MyBrowser : WebBrowser {}
Then use MyBrowser instead of the .NET one.
