I am creating a UIButton inside a UIView. If I apply a transition to the UIView the myButton_TouchUpInside touch event on the UIButton stops firing. Can anyone advise? (see edit)
(I am using Xamarin here)
UIView myView = new UIView()
{
BackgroundColor = UIColor.Black,
RestorationIdentifier = identifier,
UserInteractionEnabled = true,
ClipsToBounds = true
};
UIButton myButton = new UIButton()
{
BackgroundColor = UIColor.Red,
UserInteractionEnabled = true
};
myButton.TouchUpInside += myButton_TouchUpInside;
myButton.SizeToFit();
myButton.Frame = new CGRect(0, 10, myButton.Bounds.Width, myButton.Bounds.Height);
myView.AddSubview(myButton);
View.AddSubview(myView);
Click events fire at this point. If I add a transition they stop working after the transition has occurred, I presume they have been left behind in the transition:
var myNewFrame = new CGRect(0, 50, myButton.Frame.Width, myButton.Frame.Height);
UIView.Transition(myView, 0.5, UIViewAnimationOptions.CurveEaseIn, () => { myView.Frame = myNewFrame; }, null);
I have read that the Frame of the UIButton is the key here. I checked the Frame after adding it to the UIView and then again in the completed Action in the UIView.Transition (not shown in the code above) and it's size and position are exactly the same.
edit
It isn't the transition that's causing the issue, its the animation that follows (the UIView slides then after X seconds it fades out). Directly following the transition is this code:
UIView.Animate(0.25, 10, UIViewAnimationOptions.CurveEaseInOut, () => { myView.Alpha = 0; }, () => { myView.RemoveFromSuperview(); });
If I remove this, it works.
OK, rather than using the inbuilt delay property I wrapped it in an async method as so:
UIView.Transition(myView, 0.5, UIViewAnimationOptions.CurveEaseIn, () => { myView.Frame = myNewFrame; }, ()=> {FadeOut(duration)});
private async FadeOut(int duration){
await Task.Delay(duration * 1000);
UIView.Animate(0.25, 0, UIViewAnimationOptions.CurveEaseInOut, () => { myView.Alpha = 0; }, () => { myView.RemoveFromSuperview(); });
}
I have multiple interconnected Dojo HorizontalSlider. In the onChange event of the sliders the values of the other sliders are updated. Changing the value programmatically fires the onChange event of the corresponding slider, which again fires its own onChange event and overrides the values.
I do need to set intermediateChanges = true, which makes the priorityChange flag useless in this case. Also i tried setting up a variable that checks whether one slider is active, but due to timing issues this does not work as well.
Simplified example with two sliders:
var sliding = false;
var slider1 = new HorizontalSlider({
value: 70,
minimum: 0,
maximum: 100,
discreteValues: 101,
intermediateChanges: true,
onChange: function() {
if (sliding == false) {
sliding = true;
new_value = [...]
slider2.set("value", new_value, false);
};
sliding = false;
}
}, "slider1");
var slider2 = new HorizontalSlider({
value: 30,
minimum: 0,
maximum: 100,
discreteValues: 101,
intermediateChanges: true,
onChange: function() {
if (sliding == false) {
sliding = true;
new_value = [...]
slider1.set("value", new_value, false);
};
sliding = false;
}
}, "slider2");
slider1.startup();
slider2.startup();
I also found this example, which seems to address the same problem with Dojo Select: Dojo Select onChange event firing when changing value programatically
How to prevent firing the onChange event of a slider when changing its value programmatically?
Thank you!
Maybe a bit ugly, but you could do this:
var sliding = false;
var slider1 = new HorizontalSlider({
value: 70,
minimum: 0,
maximum: 100,
discreteValues: 101,
intermediateChanges: true,
onChange: function() {
if (sliding == false) {
sliding = true;
new_value = [...]
slider2.set("intermediateChanges", false);
slider2.set("value", new_value, false);
slider2.set("intermediateChanges", true);
};
sliding = false;
}
}, "slider1");
var slider2 = new HorizontalSlider({
value: 30,
minimum: 0,
maximum: 100,
discreteValues: 101,
intermediateChanges: true,
onChange: function() {
if (sliding == false) {
sliding = true;
new_value = [...]
slider1.set("intermediateChanges", false);
slider1.set("value", new_value, false);
slider1.set("intermediateChanges", true);
};
sliding = false;
}
}, "slider2");
slider1.startup();
slider2.startup();
Is there a way to create a non-modal dialog window using dojo? jQuery UI supports both modal and non-modal dialog boxes. I am trying to convert a SilverLight application to HTML/javascript and finding it difficult to create non-modal windows using dojo.
You can set the display of the underlay to 'none', and you will have a non-modal Dialog. To do that, set the class of the Dialog to 'nonModal' (that's just a convention I'm creating right now), and in the CSS for the page, have an entry for .nonModal_underlay.
require(['dijit/form/Button','dijit/Dialog'],
function (Button, Dialog) {
var d = new Dialog({
'title':'I am nonmodal',
'class':'nonModal'
});
});
.nonModal_underlay {
display:none;
}
you might try dojox.layout.FloatingPane
Hi Just add this in your css
.dijitDialogUnderlayWrapper{
display:none !important
}
For people that need truly modeless Dialog, Roy J provides only partial solution as the focus still is held within the Dialog. To fix this, you can copy the dijit/Dialog.js and its dijit/templates/Dialog.html to your own folder structure and rename them to ModelessDialog. Then remove the focus handler, the key handler and the underlay. Here is the full result:
