I have a plugin can open a view with a CTabFolder.I want to close the view when the tabPage closed.
So I added a DisposeListener to the Composite of the tabPage :
composite.addDisposeListener(new DisposeListener() {
#Override
public void widgetDisposed(DisposeEvent e) {
}
});
But I have no idea how to close the view.

I'm creating a web development framework with Eclipse RCP.
The wizard is creating a feature that creates a project when you press Finish.
I want to show Process Monitor at the bottom of the wizard
I wrote the code as below.
public abstract class CreateProjectWizard extends Wizard {
public CreateProjectWizard () {
...
setNeedsProgressMonitor(true);
}
...
#Override
public boolean performFinish() {
IRunnableWithProgress runnable= new IRunnableWithProgress() {
#Override
public void run(IProgressMonitor monitor) throws InvocationTargetException, InterruptedException {
...
IStatus status = createProject(input, monitor);
...
}
};
try {
getContainer().run(true, true, runnable);
}
...
return true;
}
}
How do I make the "user operation is waiting" dialog invisible?
I will let you know if you need additional information.
It looks like you should be able to call Dialog.setBlockedHandler with something that implements IDialogBlockedHandler to change this dialog (both in org.eclipse.jface.dialogs).
The blocked handler does not have to display a dialog, the default JFace handler is just:
new IDialogBlockedHandler() {
#Override
public void clearBlocked() {
// No default behavior
}
#Override
public void showBlocked(IProgressMonitor blocking,
IStatus blockingStatus, String blockedName) {
// No default behavior
}
#Override
public void showBlocked(Shell parentShell, IProgressMonitor blocking,
IStatus blockingStatus, String blockedName) {
// No default behavior
}
};
Eclipse normally replaces this with org.eclipse.ui.internal.dialogs.WorkbenchDialogBlockedHandler which shows the dialog you see (BlockedJobsDialog).
Note that this will not stop the operation waiting for the blocking jobs to finish it will just stop the dialog appearing.
In Eclipse SWT/Jface/RCP application I created dropdown menu tool button by adding IAction of style AS_DROP_DOWN to the ToolBarManager. Pressing down arrow on button invokes my dropdown menu.
I need to invoke the same menu when I press on toolbar button itself. How can I invoke the drop down menu in the IAction.run() or the IAction.runWithEvent(Event) method?
Here is simple code example:
class MyToolbarButtonsCreator {
public void createButtons( ToolBarManager aTbManager ) {
Action fooAct = new Action( "My dropdown button", IAction.AS_DROP_DOWN_MENU ) {
#Override
public void run() {
// TODO how to invoke button's dropdown menu?
}
#Override
public void runWithEvent( Event event ) {
// TODO how to invoke button's dropdown menu?
}
};
aTbManager.add( fooAct );
}
}
I am very new to Xamarin Forms development and I need a popup dialog. I found exactly what I am looking for in https://github.com/rotorgames/Rg.Plugins.Popup, but I cannot for the life of me figure out how to use it. Could someone point me to a working example or provide some direction on use? The README.md on the site is not helping me much.
I want the the popup dialog to appear when a info button is clicked in the top navigation bar. All the popup needs is 1-2 buttons (and labels) for setting user settings.
This is for Xamarin.Forms: iOS and Android.
In simple steps:
Install the plugin in all the projects
Add the PopUp in your
Xaml
Use the methods they provide on the documentacion for Show/Hide the PopUp:
Task PushAsync(PopupPage page, bool animate = true)
Task PopAllAsync(bool animate = true)
They also provide a demo, check it:
https://github.com/rotorgames/Rg.Plugins.Popup/tree/master/src/Demo
Add a reference to the library, i.e. from nuget, to all projects.
Within your Android project, add this Rg.Plugins.Popup.Popup.Init(this, savedInstanceState); inside the MainActivity.cs OnCreate method, before Xamarin Forms Inits.
And the same for the iOS project, inside AppDelegate.cs FinishedLaunching method()
//Android
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
Rg.Plugins.Popup.Popup.Init(this, savedInstanceState); /*Must add before the other Xamarin Inits*/
Xamarin.Essentials.Platform.Init(this, savedInstanceState);
Xamarin.Forms.Forms.Init(this, savedInstanceState);
}
//iOS
public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
Rg.Plugins.Popup.Popup.Init(); /* place at the top*/
....
}
Add a new ContentPage (.xaml) to your Views directory.
<?xml version="1.0" encoding="utf-8" ?>
<pages:PopupPage
xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:pages="clr-namespace:Rg.Plugins.Popup.Pages;assembly=Rg.Plugins.Popup"
xmlns:animations="clr-namespace:Rg.Plugins.Popup.Animations; assembly=Rg.Plugins.Popup"
x:Class="MyProjectName.Views.MyContentPageName">
<pages:PopupPage.Animation>
<animations:ScaleAnimation
PositionIn="Center"
PositionOut="Center"
ScaleIn="1.2"
ScaleOut="0.8"
DurationIn="400"
DurationOut="300"
EasingIn="SinOut"
EasingOut="SinIn"
HasBackgroundAnimation="True"/>
</pages:PopupPage.Animation>
<StackLayout HorizontalAlignment="FillAndExpand" VerticalAlignment="FillAndExpand">
<!-- place your layout content here ....fx a close popup button -->
<Button Clicked="CloseBtn_Clicked" Text="Close" />
</StackLayout>
</pages:PopupPage>
In the ContentPage (PopupPage) code behind file, add using Rg.Plugins.Popup.Services; and inherit from the following
using Rg.Plugins.Popup.Services;
using System;
using System.Threading.Tasks;
using Xamarin.Forms;
[XamlCompilation(XamlCompilationOptions.Compile)]
public partial class MyContentPageName: Rg.Plugins.Popup.Pages.PopupPage
{
public MyContentPageName()
{
InitializeComponent();
}
public void OnAnimationStarted(bool isPopAnimation)
{
// optional code here
}
public void OnAnimationFinished(bool isPopAnimation)
{
// optional code here
}
protected override bool OnBackButtonPressed()
{
// Return true if you don't want to close this popup page when a back button is pressed
return true;
}
// Invoked when background is clicked
protected override bool OnBackgroundClicked()
{
// Return false if you don't want to close this popup page when a background of the popup page is clicked
return false;
}
private async void CloseBtn_Clicked(object sender, EventArgs e)
{
await PopupNavigation.Instance.PopAsync(true);
}
}
From the .xaml.cs page, where you would like to open the popup, add this:
using System;
using Xamarin.Forms;
using Xamarin.Forms.Xaml;
using Rg.Plugins.Popup.Contracts;
using Rg.Plugins.Popup.Services;
public partial class MyOtherPage : ContentPage
{
private IPopupNavigation _popup { get; set; }
private MyContentPageName _modalPage;
public MyOtherPage()
{
_popup = PopupNavigation.Instance;
_modalPage = new MyContentPageName();
}
protected override void OnAppearing()
{
base.OnAppearing();
_popup.Popped += Popup_Popped;
}
protected override void OnDisappearing()
{
base.OnDisappearing();
_popup.Popped -= Popup_Popped;
}
private async void Tapped_OpenModal(object sender, EventArgs e)
{
await _popup.PushAsync(_modalPage);
}
/// <summary> Triggered when the MyContentPageName popup is closed "PopAsync()" </summary>
private async void Popup_Popped(object sender, Rg.Plugins.Popup.Events.PopupNavigationEventArgs e)
{
/* add your logic here, if necessary */
}
}
*Note: If your modal simply displays static content, there is no need for a _popped event delegate within the OnAppearing()/OnDisappearing().
I trying to navigate between XAML pages in grid app. for this i have added a added a new XAML and a button in XAML and cs code for button event is
private void OnClick(object sender, RoutedEventArgs e)
{
Frame.Navigate(typeof (GroupedItemsPage));
}
on clicking this button my app should navigate to GroupedItemsPage, but instead it raises an null exception
try this :
private void OnClick(object sender, RoutedEventArgs e)
{
this.Frame.Navigate(typeof (GroupedItemsPage));
}
Please have a look there, too.
Iam developing a RCP application which consists of views and editors. I can change the values and edit the values of some parameters in editor. When a value has been changed, i need to make the editor dirty as well as would also like to enable the save button. Till now, i have not implemented my save button. Could anyone guide me how to make the save button enabled as well as how can i make an editor dirty when some modifications happen in editor.
Thanks in advance. Any help will be greatly appreciated.

Here is an overview of the Form editor logic, hop it will help you.
public class TestEditor extends FormEditor {
#Override
protected void addPages() {
// this method is called when the editor is being created
// to add the necessary pages
// page classes should be like following
// class TestEditorPage extends FormPage
try {
TestEditorPage pageTest = new TestEditorPage(this);
addPage(pageTest);
} catch (PartInitException e) {
}
}
#Override
public void doSave(IProgressMonitor monitor) {
// this method will be called on save action
// (or Ctrl + s shortcut)
}
#Override
public void doSaveAs() {
// this method will be called on save-as
//call (or Ctrl + Shift + s shortcut)
}
#Override
public boolean isSaveAsAllowed() {
// put here the call to the logic that
// check if the save is allowed
return true;
}
#Override
public boolean isDirty() {
// Here the call for the logic that
// defines if the editor is dirty or not
return true;
}
}
