I need to be able to hide the navbar and tabbar when I tap on the view and show it again when tapped again. Is this possible in Monotouch?
Anything that is possible with the native platform is possible with MonoTouch.
There are dozens of ways of achieving this. Perhaps the simplest thing to do is to create your own UIViewController that will host only the information you want and calling:
var myNewController = new MyNewController ()
myNewController.View.TouchDown += delegate {
myNewController.DismissViewControllerAnimated (false);
};
PresentModalViewController (yourNewController, false);
Then your myNewController must contain some code to add the actual contents that you want to show in full screen.

I am creating a UIViewController which have an animation on it and I want it to be displayed while "loading" or changing views. Is there a way so I can show that view in top of the others while they're doing their business logic and when they're done call in their respectives ViewDidLoad functions, a call to "hide" this facade view?
I think you want to display loading overlay which has your own custom animation and you want to show/hide this loading overlay on top of any View or ViewController. If my understanding is correct then you can achieve this as follows:
Suppose loadingOverlay is your animation view instance.
Assign some unique Tag to this:
loadingOverlay.Tag = 1678;
This can be any number which uniquely identifies your loading overlay view from all other views from UIWindow in any ViewController.
Show:
UIWindow myKeyWindow = UIApplication.SharedApplication.KeyWindow;
myKeyWindow.AddSubView(loadingOverlay);
Hide:
var loadingOverlay = myKeyWindow.ViewWithTag(1678);
//Remove completely
loadingOverlay?.RemoveFromSuperView();
//OR
//Simply hide it
loadingOverlay?.Hidden = true;
Note: If you want to use Hidden property, then you have to make sure that you add this view into UIWindow only once.
So, ideally, anything which you want to display on top of anything,
should go into KeyWindow (UiWindow)
Hope this helps!!
I have a single AppBar declared in default.html for use throughout my application.
On some of the pages I need to show the App Bar and in some of the I need to hide the AppBar.
So far, my efforts to find the methods to hide and show the AppBar have met a dead end.
The documentation on MSDN says:
AppBar.hide method :
Hides the app bar on Windows and the secondary command menu on Windows Phone.
So, that method only hides the AppBar for Windows and not for a Windows Phone project.
I have also tried giving display:none as a CSS style, to no effect.
Any help will be appreciated :)
AppBar.Hide hides the secondary command bar on Windows Phone, not the main AppBar. If you want the entire AppBar to go away then this isn't the right property.
The easiest way is to declare the AppBar on pages that you want to show it and to leave it out on pages that you don't want it, but you should be able to hide it by disabling the AppBar on pages that you don't want it on.
I just modified the appbar-commands.js file in the HTML AppBar control sample as follows and the appbar hides and shows as I click the hide and show buttons:
// These functions are used by the scenario to show and hide elements
function doShowItems() {
document.getElementById('commandsAppBar').winControl.disabled = false;
//document.getElementById('commandsAppBar').winControl.showCommands([cmdFavorite, cmdCamera]);
document.getElementById('scenarioShowButtons').disabled = true;
document.getElementById('scenarioHideButtons').disabled = false;
}
function doHideItems() {
document.getElementById('commandsAppBar').winControl.disabled = true;
//document.getElementById('commandsAppBar').winControl.hideCommands([cmdFavorite, cmdCamera]);
document.getElementById('scenarioHideButtons').disabled = true;
document.getElementById('scenarioShowButtons').disabled = false;
}
I also confirmed with the single-page navigation model navigating between two pages. If you aren't seeing the appbar hide and show when disabled and enabled then make sure you are calling the code to disable / enable the appbar. The PageControl's ready function may not be called when returning to a cached page.
You'll have to do it with C#, You can simply just type.. (If your appbar is called ApplicationBar)
ApplicationBar.Visibility = Visibility.Collapsed;
This will instantly hide the AppBar! If you want your HTML Page to perform this action, it will be much complicated.
Cheers
I think you can try below step in your code.
Add a event listener for appbar beforeshow
In code of before show Check a condition with specific page name
Like : if (WinJS.Navigation.location.match("test.html"))
According to you condition you can Disable your appbar.
All the best..!!
I need to handle multiple panels, containing variuous data masks. Each panel shall be visible using a TreeView control.
At this time, I handle the panels visibility manually, by making the selected one visible and bring it on top.
Actually this is not much confortable, especially in the UI designer, since when I add a brand new panel I have to resize every panel and then design it...
A good solution would be using a TabControl, and each panel is contained in a TabPage. But I cannot find any way to hide the TabControl buttons, since I already have a TreeView for selecting items.
Another solution would be an ipotethic "StackPanelControl", where the Panels are arranged using a stack, but I couldn't find it anywhere.
What's the best solution to handle this kind of UI?
You need a wee bit of Win32 API magic. The tab control sends the TCM_ADJUSTRECT message to allow the app to adjust the tab size. Add a new class to your project and paste the code shown below. Compile. Drop the new control from the top of the toolbox onto your form.
You'll get the tabs at design time so you can easily switch between pages. The tabs are hidden at runtime, use the SelectedIndex or SelectedTab property to switch between "views".
using System;
using System.Windows.Forms;
class StackPanel : TabControl {
protected override void WndProc(ref Message m) {
// Hide tabs by trapping the TCM_ADJUSTRECT message
if (m.Msg == 0x1328 && !DesignMode) m.Result = (IntPtr)1;
else base.WndProc(ref m);
}
}

For the above,
You need to set the following properties of TabControl.
tabControl.Multiline = true;
tabControl.Appearance = TabAppearance.Buttons;
tabControl.ItemSize = new System.Drawing.Size(0, 1);
tabControl.SizeMode = TabSizeMode.Fixed;
tabControl.TabStop = false;
I want to create a JavaFX table that, in the cells of one column, allows the user to edit XHTML text. I only need very basic formatting capabilities like bold, italic, striketrough.
I have already managed to implement this by using my own subclass of TableCell and using a WebView for each cell (HTMLEditor would of course have been another choice, but my guess is that for my requirements, WebView should be sufficient).
However, to make editing comfortable for the user, I need the following features:
1. The cell height needs to resize if the user enters multi-line text.
2. A context menu (or, if not possible, some other menu or button) should allow formatting parts of the text in a cell as described above (bold, italic..)
Has anybody been successful in implementing something similar ? I have seen suggestions on the web, but they rarely included code samples.
I have succedded doing something similar.
I figured I can share some of the basic clues that allowed me to achieve it.
Resize the whole WebView. For that, the whole WebView must be an editable html page. You achive that by setting contenteditable to true:
<body contenteditable='true' id='content'></body>
You can have a context menu over a webview. But it is something tricky, as you must first disable the original context menu associated to it.
WebView editView;
...
EventDispatcher originalDispatcher = editView.getEventDispatcher();
editView.setEventDispatcher(new WebmenuEventDispatcher(originalDispatcher));
And this is the event dispatcher class:
public class WebmenuEventDispatcher implements EventDispatcher {
private EventDispatcher originalDispatcher;
public WebmenuEventDispatcher(EventDispatcher originalDispatcher) {
this.originalDispatcher = originalDispatcher;
}
#Override
public Event dispatchEvent(Event event, EventDispatchChain tail) {
if (event instanceof MouseEvent) {
MouseEvent mouseEvent = (MouseEvent) event;
if (MouseButton.SECONDARY == mouseEvent.getButton()) {
mouseEvent.consume();
// Show our own menu
cmEdit.show(editView.getScene().getWindow(), mouseEvent.getScreenX(), mouseEvent.getScreenY());
}
}
return originalDispatcher.dispatchEvent(event, tail);
}
}
Now, for setting the font from within that menu, you need a bidirectional Java<->javascript bridge and use some javascript in the webview side.
NOTE: There are two similar SO questions (1) (2), but neither of them provides an answer.
TL;DR: How can one dismiss the keyboard in a MonoTouch.Dialog by letting the user touch any empty space in the view?
I'm writing an app using MonoTouch.Dialog and a UITabBarController. One of my tabs is "Settings"...
When the user starts typing, the keyboard obstructs the tabbar...
Using MonoTouch.Dialog, the only way to dismiss the keyboard is to go to the last field and press the "return" key. Considering the fact that the user cannot press any tab until the keyboard is gone, I would like a better way to do it. Namely, to dismiss if the user taps anywhere else on the screen.
Without MonoTouch.Dialog, it's a snap: simply override TouchesBegan and call EndEditing. But this doesn't work with MT.D. I've tried subclassing DialogViewController and overriding TouchesBegan there, but it doesn't work. I'm currently at a loss.
Or, I wonder, would I be better off ditching the tabbar so I can use a UINavigationController with a "Back" button on top, which won't be hidden by the keyboard?
I suggest you use a tap gesture recognizer that will not cause interference with the TableView event handlers:
var tap = new UITapGestureRecognizer ();
tap.AddTarget (() => dvc.View.EndEditing (true));
dvc.View.AddGestureRecognizer (tap);
tap.CancelsTouchesInView = false;
You missed my question about it also: Can the keyboard be dismissed by touching outside of the cell in MonoTouch.Dialog?
:-)
This is my #1 feature request for MonoTouch.Dialog.
To answer your question: No. It is not possible. I have searched and asked around and have not found any answers.
I assume because it is just a sectioned (grouped) table and if it wasn't sectioned, there wouldn't be any spot to click. However, that is just my speculation.
I wish that miguel or someone that works on monotouch would answer this and say if it is even possible. Possibly a future enhancement?
I figured out a workaround that satisfies me well enough, so I'm answering my own question.
// I already had this code to set up the dialog view controller.
var bc = new BindingContext (this, settings, "Settings");
var dvc = new DialogViewController (bc.Root, false);
// **** ADD THIS ****
dvc.TableView.DraggingStarted += (sender, e) => {
dvc.View.EndEditing (true);
};
This will dismiss the keyboard whenever the user drags the view a little bit. There's no touch event I could find associated with the tableview, so this is the next best thing. I'd welcome any other ideas. Cheers!
One workaround to use the dragging gesture instead of the tap as proposed (that do not interfere with the table view gestures) is to override MonoTouch.Dialog.DialogViewController.SizingSource (or MonoTouch.Dialog.DialogViewController.Source if you don't want uneven rows) and give it to the DialogViewController. I don't know if it is very clean or safe.
public class CustomTableViewSource : MonoTouch.Dialog.DialogViewController.SizingSource
{
public CustomTableViewSource(MonoTouch.Dialog.DialogViewController dvc) : base(dvc)
{
}
public override void DraggingStarted(UIScrollView scrollView)
{
base.DraggingStarted(scrollView);
if (scrollView != null)
{
scrollView.EndEditing(true);
}
}
}
