I need to build a custom pan for openlayer(ol3) map using press and drag mouse middle key only. This is what i need.
new ol.interaction.DragPan({
condition: function(event) {
// return event.originalEvent.ctrlKey
// need event for mouse middle key instated of ctrl
}
});
Any suggestion?

Problem:
Using "TextInput" in react native shows keyboard, and on pressing return, cursor moves to new line, however at this i do not have "done" button to hide the keyboard.
Again, there is props called "returnKeyType={done}, which adds "done" button but now "return" button is gone. I believe user could tap to new line inside "TextInput" box, but it seems to highlight the words typed.
Solution attempt:
Like in numeric keyboard, i thought there should be some props to add "done" button on top of keyboard so that we will have both "return" and "done" botton visible at the same time, but i could not find it.
... another option is i could create my own component with done button, and wrap keyboard as child, but i could not figure out how i do it.
This is basic component, i believe there must be some elegant way to do it. any help is appreciated.
You cannot have done and newline button at the same time.
There should only be one submitting button in keyboard.
But you can make a similar work around.
Custom Button
First option is making custom button like you mentioned.
Make a "Done" button next to your textfield or above the keyboard.
onSubmitEdit
Second option is using onSubmitEdit
Make a custom function that controls what return button should do.
e.g.)
const [textInputValue, setTextInputValue] = useState("");
const returnPressed = () => {
if(need_new_line){
setTextInputValue(textInputValue+"\n");
} else {
returnFunction();
}
};
return (
<TextInput
value={textInputValue}
onChangeText={(text)=> setTextInputValue(text)}
onSubmitEditing={()=> returnPressed()}
/>
);
I'm using WinJS.UI.Animation.pointerDown and WinJS.UI.Animation.pointerUp within a WinJS repeater's item template.
The problem is if a user holds their finger or the mouse button down on an item and moves off it, the pointerUp animation doesn't seem to fire or it fires but has no effect because the element that the up event is on is not the same as the one before. The best example of this is in the animation sample in example 6 (tap and click). Hold down the mouse button on a tile and move it off. It will stay in it's animated state and won't fire the pointerup event. Here's the code I'm using.
How can I cancel the pointerdown animation if the user moves off the element?
target1.addEventListener("pointerdown", function () {
WinJS.UI.Animation.pointerDown(this);
}, false);
target1.addEventListener("pointerup", function () {
WinJS.UI.Animation.pointerUp(this);
}, false);
target1.addEventListener("click", function () {
//do something spectacular
}, false);
I'm using the click event to commit the click action so that the right click remains clear for launching the navigation at the top of the app.
Have you tried adding an event listener for pointerout? That's the event that's dispatched when a pointing device (e.g. mouse cursor or finger) is moved out of the hit test boundaries of an element.
See the docs on pointer events here:

I try to implement a custom ContextMenu in a LongListSelector.
I'm not using the ContextMenu from Microsoft.Phone.Controls.Toolkit, it's basically the same as in the Rowi App:
(source: hiddenpineapple.com)
Approach 1
My list item toggles a VisualState on hold and an overlay is shown with controls in it.
The problem
I can't find a way to go back to the default state when the user clicks outside of the list item (as in the default ContextMenu).
Approach 2
I've implemented a custom template for the toolkit ContextMenu which looks exactly the same. I had to move its margin top to -itemHeight, as by default it is below the item.
The problem
The problem with this solution is, that it automatically closes itself when opening and I couldn't figure out how to avoid this.
Another problem was that it didn't work well with TiltEffect.IsTiltEnabled from the Toolkit (visual problems).
I need your help
Any suggestions on how to get this working?
Answer
Thanks to Cheese, now I know how to properly close the menu when the user clicks outside.
His suggestion was to get the coordinates of a Tap event on the current page, and check if it's inside the menu. When not, close the menu.
So I added a Tap listener to the page when the menu opens, and removed it when the menu closes. From the page listener I got the event coordinates and could check if it's inside the control which holds the menu (same size and position). I received the position of the control with Point leftUpperPoint = control.TransformToVisual(page).Transform(new Point(0, 0)) and the rightLowerPoint by adding the ActualWidth and ActualHeight.
But then I realized:
Why should I even calculate if the tap is inside the menu? I always want to close the menu when the user taps anywhere on the screen. If it's outside, yes. If it's on a menu button, yes.
Another modification I made was to listen for MouseLeftButtonDown instead of Tap as it also triggers when the user swipes.
So I removed this code and came up with the following:
private void ToggleMenu(object sender, System.Windows.Input.GestureEventArgs e)
{
PhoneApplicationFrame frame = ((PhoneApplicationFrame)Application.Current.RootVisual);
VisualState state = this.States.CurrentState;
if (state == null || state.Name == "DefaultState")
{
frame.MouseLeftButtonDown += MouseDownDelegate;
this.State = "MenuState";
}
else
{
frame.MouseLeftButtonDown -= MouseDownDelegate;
this.State = "DefaultState";
}
}
private void MouseDownDelegate(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
ToggleMenu(sender, null);
}
This works perfectly!
Thanks to Cheese for the hint.
Something like this by #denniscode http://dotnet.dzone.com/articles/rowi-show-tap-menu
Approach 1 problem
The best solution would be:
Get the menus coordinates, when user makes a tap - you check are tap coordinates on menu or not, if not - dissmiss - simple.
Approach 2 problem
I guess you had some button in a corner and when you tapped on it - nothing happened? And when you dissmissed the Tilt all worked. It seems that tilt works faster than a click, so, tilt changes the button coordinates, and device thiks you have missed/or dragged off
You can use what #ScottIsAFool suggested and maybe create another Dependency Property on your TapMenu control of type UIElement named CloseWhenTappedElement and automatically listen for Tap events inside your control once set. For example
<Grid x:Name="TapArea"/>
<TapMenu CloseWhenTappedElement="{Binding ElementName=TapArea"}/>
Im trying to fire a click event on a tool bar button Dojo 1.8.1.
<div data-dojo-type="dojox.mobile.ToolBarButton" class="backButton" moveTo="cartView" transition="slide">
I have tried
function backClick(){
var backButton = dojo.query(".backButton", dojo.byId(currentView.id))[0];
writeLog("backClick::"+backButton);
if(backButton){
var backDijit = dijit.registry.byId(backButton.id);
writeLog("backDijit::" + backDijit.id);
writeLog("emit Click");
backDijit.emit("click", {bubbles:true});
writeLog("emit mousedown");
backDijit.emit("mousedown",{bubbles:true});
writeLog("emit mouseup");
backDijit.emit("mouseup",{bubbles:true});
writeLog("touchstart");
backDijit.emit("touchstart");
writeLog("touchEnd");
backDijit.emit("touchend");
}else{
//Exit App notification
navigator.app.exitApp();
}
}
mousedown/mouseup combo works on the browser.
But on the device it does not work(Android). What is the event that i have to send to 'click' the button on a device?
It seems that the sequence of events that will activate the toolbar button 'click' on a touch device is touchstart followed by touchend.
I suppose that your example do not work because the synthetic touch events that you are emitting do not contains any data, which fails the different methods that handle it.
Another way to trigger the click handler of the toolbar button would be to call its _onClick method.
I am using ZedGraph and I want to zoom to a selected area by holding down Ctrl and dragging the box with the left mouse button instead of clicking and dragging with the middle mouse button.
The default behavior is to zoom with just the left mouse button and to pan with the middle mouse button, but I have switched these two operations already.
Does anyone have any idea how to make panning be called by clicking and dragging with the left button (without holding down Ctrl) and zooming be called by holding down Ctrl and then clicking and dragging with the left button?
The ZedGraphControl allows Pan & Zoom to be controlled through properties of the control. To enable panning with just the left mouse button:
zg1.PanButtons = MouseButtons.Left;
zg1.PanModifierKeys = Keys.None;
and to enable Zoom with Ctrl+Left mouse button:
zg1.ZoomButtons = MouseButtons.Left;
zg1.ZoomModifierKeys = Keys.Control;
The designer properties window doesn't seem to want to let you just specify Control for the Modifier Keys, so you'll have to put it in code - the Form's Load event handler, for example.
Have you try it by code using:
zg.GraphPane.XAxis.Scale.Min = xxxx;
zg.GraphPane.XAxis.Scale.Max = yyyy;
//and
zgc.ScrollGrace = 0.1;
