I'm using BlackBerry-10 Cascades to develop an app. I want a context menu to open on the right when I click a button. Currently I have it so that the menu opens after a press- hold of the button but I need it to open as soon as the button is tapped. I've tried finding a way to do this but cannot find it in the documentation. Is there any way I can invoke the context menu from the onclicked method of a button press?
BTW: this is all in QML
I am not really familiar with the controls available on blackberry-cascades, but, it seems like it should be as simple as moving the code from the onPressAndHold signal handler to the onClicked signal handler. For better help you should post the relevant snippets of your code along with the imports so we can find more info to help you in your particular scenario.
actions: [
//! [0]
ActionItem {
title: _webMaps.viewModeTitle
imageSource: "asset:///images/map.png"
ActionBar.placement: ActionBarPlacement.OnBar
onTriggered: {
_webMaps.nextViewMode()
map.setMapType(_webMaps.viewMode);
}
},
//! [0]
ActionItem {
title: qsTr("Waterloo")
imageSource: "asset:///images/pin.png"
ActionBar.placement: ActionBarPlacement.InOverflow
onTriggered: {
map.setCenter(43.468245, -80.519603);
}
}
]
try this sample..
In theory you should be able to do it but there are two problems that I see with this idea:
A context menu is supposed to be posted in the context of another UI element. I'm not sure what context menu items you might have for a button. If you are posting the context menu in the context of some other control then you will confuse your users.
The age old issue of non-conformance with the UI style guide of the platform. You will be expecting your uses, who have invested time in learning how to operate the BB10 UI, to now learn a different set of interface semantics.
There is a Context menu api in the BlackBerry Platform Services (BPS) library that you can use.
https://developer.blackberry.com/native/reference/core/com.qnx.doc.bps.lib_ref/topic/manual/dialog.h_functionscontextmenufunctions.html?f=dialog
It is not "Cascades functionality" per se, but you can use it from within a Cascades application. Note that it is a C based api so you would have to create some kind of "helper class" and expose it to QML yourself.
Try this sample code for open context menu on button clicked.

I'm building a website using Wix.com and I'm trying to add a feature with code. I want a button to appear only when I hover over a document on the page. So far the button appears the way I want, but when I try to click on it, it keeps flickering so it's hard for me to click it.
I'm pretty new to this so I just tried basic debugging But still I don't know why this is happening. Also, I couldn't find much help from Wix forum
here are the code and a screenshot from the site (code examples is the button)
let rollLeft = {
"duration": 200,
"direction": "left"
};
let rollRight = {
"duration": 200,
"direction": "right"
};
$w.onReady(function () {
//TODO: write your page related code here...
});
export function document15_mouseIn(event) {
//Add your code for this event here:
if(!$w('#button1').isVisible)
{
$w('#button1').show("roll", rollLeft);
}
}
export function document15_mouseOut(event) {
//Add your code for this event here:
if($w('#button1').isVisible)
{
$w('#button1').hide("roll", rollRight);
}
}
Without seeing it in action this is a bit of a guess, but it looks like when you move to the button, you leave the pdf, causing the button to hide.
I can think of at least two ways to get around this:
Add a delay to the effect options to give a user enough time to click the button before it starts to disappear.
Add a transparent box beneath the file icon and the button. Use that box to trigger the show and the hide on hover, instead of the file icon. That way the hide won't trigger when the user tries to click the button.
Does anyone know if it's possible to add a button in the KeystonJs admin for example in the User model. I would like to have a set of fields and enable an admin to click "Add another" which will create a new field/row of fields.
So I just want that button to call a function. Something like this:
{ addItem: { type: Types.Button, label: 'Add another', actions: addItem() }}},
To add a button on KeystoneJs Admin GUI, you have to modify and build upon its's source. There is no way you can do that in this release (4.0).
There are discussions on their GitHub issues page and it may land in next version but no promises made yet.
I am beginning with OPA5 tests in UI5 and I created a context menu that is shown when a button, label or an image is right-clicked or if user holds it on touch screen.
Now I need to write an OPA5 test for this. I can perform left-click using new sap.ui.test.actions.Press() but I am not able to do right-click or long-press.
https://sapui5.hana.ondemand.com/#/api/sap.ui.test.actions/overview
Can someone help, please?
I believe I would be able to write it in jQuery. And as UI5 is based on jQuery there should be a way but I do not know how to combine jQuery and UI5.
If your Control has an event for RightClick, Hold etc. you should be able to call this Event in an Opa test somehow like:
iRightClickMyControl: function () {
return this.waitFor({
id: "myControlId",
viewName: "myView",
actions: function (oControl) {
oControl.RightClick();
}
errorMessage: "myControl was not found."
});
}

I'm learning to work with QML and Qt Quick Controls 2 and try to figure out how to write "proper" applications with it (endgame is a small prototype for embedded devices).
One thing I'm missing is a simple and explicit way to build multi-page applications: there is StackView, TabView and SwipeView, but there is nothing like SimpleView, a component that I could put Page components into and then switch them via custom actions. Currently, I'm mis-using the SwipeView to achieve something similar, by setting interactive property to false, but I have to wonder whether this is a proper way.
So, which is the most generic "page container" component in Qt Quick Controls 2?
Take a look at StackLayout from Qt Quick Layouts. It's a stack of arbitrary items, where you can control the index of the currently visible item.
StackLayout {
anchors.fill: parent
currentIndex: 1
Page {
// ...
}
Page {
// ...
}
}
In addition to the 'back' button functioning as expected, I need to asynchronously invoke a function to update some db tables and refresh the UI.
Prior to making this post, I did some research and tried the following on this...
<h1 data-dojo-type="dojox.mobile.Heading" id="hdgSettings" data-dojo-props="label:'Settings',back:'Done',moveTo:'svStart',fixed:'top'"></h1>
dojo.connect(dijit.registry.byId("hdgSettings"), "onclick",
function() {
if (gblLoggerOn) WL.Logger.debug(">> hdgSettings(onclick) fired...");
loadTopLvlStats();
});
Since my heading doesn't have any other widgets than the 'back' button, I thought that attaching this event to it would solve my problem... it did nothing. So I changed it to this...
dojo.connect(dijit.registry.byId("hdgSettings")._body, "onclick",
function() {
if (gblLoggerOn) WL.Logger.debug(">> hdgSettings(onclick) fired...");
loadTopLvlStats();
});
As it turns out, the '._body' attribute must be shared by the Accordion widget that I just happen to use as my app's main UI component, and any attempt to interact w the Accordion rendered my entire app useless.
As a last resort, I guess I could simply forgo using the built-in 'back' button, and simply place my own tabBarButton on the heading to control my app's transition and event processing.
If the community suggests that I use my own tabBarButton, then so be it, however there has to be a way to cleanly attach an event to the built-in 'back' button support.
Thoughts?
The following should do the trick:
var backButton = dijit.registry.byId("hdgSettings").backButton;
if (backButton) {
dojo.connect(backButton, "onClick", function() { ... });
}
Remarks:
The code above should be executed via a dojo/ready call, to avoid using dijit's widget registry before it gets filled. See http://dojotoolkit.org/reference-guide/1.9/dojo/ready.html.
Note the capitalization of the event name: "onClick" (not "onclick").
Not knowing what Dojo version you use (please always include the Dojo version information when asking questions), I kept your pre-AMD syntax, which is not recommended with recent Dojo versions (1.8, 1.9). See http://dojotoolkit.org/documentation/tutorials/1.9/modern_dojo/ for details.
