I have a GTK notebook with multiple tabs. Each tab label is a composite container containing, among other things, a button I want to use to close the tab. The button has a handler for the "clicked" signal.
When the signal is called, I get the button widget and "EventArgs" as a parameter.
I need to determine the page number based on the button widget, but myNotebook.PageNum(buttonWidget) always returns -1. I've even tried buttonWidget.Parent which is the HBox which contains the widget.
Any ideas on what I can do or what I am doing wrong?
One easy work around is to pass the page number to your button's Clicked event as you construct the buttons.
for (int page = 0; page < n; page++){
int the_page = page;
NotebookPage p = new NotebookPage ();
...
Button b = new Button ("Close page {0}", the_page);
b.Clicked += delegate {
Console.WriteLine ("Page={0}", the_page);
};
}
The "the_page" is important, as it is a new variable that will be captured by the delegate.

Anyone knows automation script to verify a view (homePage/Browse) is scrollable or not. i can use ScrollTo(id) which is at the bottom of the page. But it is not a correct method to do, as test case passes if that element present in 1st page
Basically You cannot. You could try to cast the view to ScrollView class however any custom view can implement scroll.
Get the coordinates of any particular element like button etc unique element.
Swipe using driver.swipe() to 100 or more pixels.
And get the coordinates of that element again and check whether x or y coordinates changed or not.
This will let you know whether it is a single page application or more to scroll.
Basically there is no API to check the view is scrollable or not but if you still require this then you can do work around
#Test
public void testVerticalScroll()
{
//Try to Scroll till the 15th row
driver.scrollTo("List item:15");
//Assert that the 1st row is not visible.
Assert.assertFalse( driver.findElement(By.name("List item:01")).isDiaplyes())
//Assert that the 15th row is not visible.
Assert.assertTrue( driver.findElement(By.name("List item:15")).isDiaplyes())
}
You can consider the last visible element as "YourText" But this is
just a workaround that needs to be customized for each page.
Here we are using swipe until we find the element. In this case, the last visible element indicates the margin of the page.
Dimension dimensions = driver.manage().window().getSize();
Double screenHeightStart = dimensions.getHeight() * 0.5;
int scrollStart = screenHeightStart.intValue();
System.out.println("s="+scrollStart);
Double screenHeightEnd = dimensions.getHeight() * 0.2;
int scrollEnd = screenHeightEnd.intValue();
for (int i = 0; i < dimensions.getHeight(); i++) {
driver.swipe(0,scrollStart,0,scrollEnd,2000);
if (driver.findElement(By.name("YourText")).size()>0)
exit;
}
driver.findElement(By.name("YourText")).click();
There is a way to check it. You have to find a layer that you will target for example:
MobileElement scrollableLayer= driver.findElementById("elementID");
Then you will extract attribute value "scrollable" of that element like this:
String scrollableState = scrollableLayer.getAttribute("scrollable");
And then you can check if the String value is true or false.
if (scrollableState.equals("true")){System.out.println("it's scrolable"); }else{System.out.println("it's not scrolable");}
Or you can do whatever you want with it :)
how do I find out if my custom widget has focus in Dojo?
i have dojo editor i wnat to know if the editor has already focus or not?
you can use the module dijit/focus to find out the focus
FROM DOJO DOCS
Tracking active widgets
At any point in time there is a set of (for lack of a better word)
“active” or “focused” widgets, meaning the currently focused widget
and that widget’s ancestors. “Ancestor” can mean either DOM ancestor
(ex: TextBox –> Form), or a logical parent-child relationship (ex:
TooltipDialog –> DropDownButton).
For example, if focus is on a TextBox inside a TabContainer inside a
TooltipDialog triggered by a DropDownButton, the stack would be
TextBox –> ContentPane –> TabContainer –> TooltipDialog –>
DropDownButton.
The activeStack[] parameter indicates this set of widgets, and an app
can monitor changes to activeStack[] by:
require([ "dijit/focus" ], function(focusUtil){
focusUtil.watch("activeStack", function(name, oldValue, newValue){
console.log("Focused widget + ancestors: ", newValue.join(", "));
});
});
the question in title has a different answer than the one in the descriptions.
there are two ways achieving the question in the title, by using dojo's focusUtil ("dijit/focus"). both ways give you something that you could find the widget using it and the dijit's registry ("dijit/registry").
focusUtil.curNode: gives you the DOM Node that currently has the focus. the function below, you could get the widget reference.
function getWidgetByNode(node){
var result;
while (!result && node){
result = registry.byNode(node);
if (node.parentElement)
node = node.parentElement;
else
node = null;
}
return result;
}
var focusedWidget = getWidgetByNode(focusUtil.curNode)
focusUtil.activeStack: gives you an array of the widgets (parent to child) that has the focus. so the last item in the array is the direct widget which has the focus. index values are widget ids, so you should get the widget by the following code
var focusedWidgetId = focusUtil.activeStack[focusUtil.activeStack.length-1];
var focusedWidget = registry.byId(focusedWidgetId);
now if you want to know if the currently focused widget is some specific one, it depends on what you have in hands from that specific widget:
widget itself: like the return values of above samples. now you have to compare if these are the same thing. you can not compare two widget objects using the == operator. you could compare their ids like this:
myWidget.id == focusedWidget.id
widget's id: this way you just easily get the id of the current node from focusUtil and compare it with the id you have liek this:
myWidgetId == focusedWidgetId
references:
http://dojotoolkit.org/reference-guide/1.9/dijit/focus.html
http://dojotoolkit.org/reference-guide/1.9/dijit/registry.html
require([ "dijit/focus" ], function(focusUtil){
var activeElement = focusUtil.curNode; // returns null if there is no focused element
});
check blow url here you can see some examples
http://dojotoolkit.org/reference-guide/1.8/dijit/focus.html#dijit-focus
a) For dojo 1.6: call dijit.getFocus(). This will return an object containing the currently focused dom node, among other things (selected text, etc.). To get the corresponding widget, simply do:
var activeElement = dijit.getEnclosingWidget(dijit.getFocus().node);
This is the full reference for dijit.getFocus(), from the source code:
// summary:
// Called as getFocus(), this returns an Object showing the current focus
// and selected text.
//
// Called as getFocus(widget), where widget is a (widget representing) a button
// that was just pressed, it returns where focus was before that button
// was pressed. (Pressing the button may have either shifted focus to the button,
// or removed focus altogether.) In this case the selected text is not returned,
// since it can't be accurately determined.
//
// menu: dijit._Widget or {domNode: DomNode} structure
// The button that was just pressed. If focus has disappeared or moved
// to this button, returns the previous focus. In this case the bookmark
// information is already lost, and null is returned.
//
// openedForWindow:
// iframe in which menu was opened
//
// returns:
// A handle to restore focus/selection, to be passed to `dijit.focus`.
b) For dojo 1.7 and up, use dijit/focus:
require([ "dijit/focus" ], function(focusUtil) {
var activeElement = focusUtil.curNode; // returns null if there is no focused element
});
My application has a WinJS AppBar control at the bottom of the screen. I use .showOnlyCommands(buttonsToShowArray) to show and hide buttons on ListView itemSelectionChanged event.
The problem I have right now is that when every I call .showOnlyCommands, the buttons to be hidden (or you may say "replaced") are going to flash on the top of the screen.
I tried to use the Microsoft sample app, this doesn't happen. I tried to use .showCommands + .hideCommands method, it is the same behavior. Note that this didn't happen before the Release Preview version of Win8.
I have no idea what is going on. Any idea?
EDIT:
I did further investigation, the problem happens on hideCommands. Say I have 3 buttons displayed on the appbar. I call hideCommands to hide all 3 buttons. The icon of the 3 buttons would disappear on the appbar, then pile up at the top-left corner of the screen and then disappear. (i.e. there would be a flash of 3 piled up buttons at the corner of the screen).
You may be invoking showOnlyCommands when the AppBar is in the process of 'showing'. I've found that when calling these methods in the beforeshow or aftershow handler that this happens. This quote from Animating your UI sheds light on why:
Use fade in and fade out animations to show or hide transient UI or controls. One example is in an app bar in which new controls can appear due to user interaction.
The sample app shows/hides the buttons before the appbar is shown. You may be calling show on the app bar before calling showOnlyCommands.
A temporary hack for this problem is:
Set the button be invisible before calling showOnlyCommands or HideCommands.
Here is the code that I use for now:
/*
* #param {WinJS.UI.AppBar} appbar winControl
* #param {Array} array of appbar buttons to be shown
*/
function showOnlyCommands(appbarControl, buttonsToShow) {
var toShow = {};
for (var i = 0; i < buttonsToShow.length; i++) {
toShow[buttonsToShow[i].id] = true;
}
for (var i = 0; i < visibleButtonsList.length; i++) {
var id = visibleButtonsList[i].id;
if (!toShow[id]) {
// set the display property of the buttons to be hidden to "none"
var button = document.getElementById(id);
if (button) {
button.style.display = 'none';
}
}
}
// update the visible buttons list
visibleButtonsList = buttonsToShow;
// Note that we don't need to set the "display" property back for the buttons,
// because WinJS.UI.AppBar.showOnlyCommands would set it back internally
appbarControl.showOnlyCommands(buttonsToShow);
}
I need to show a virtual keyboard when the user selects an input text field in a webpage. This code runs on an set top box.
I am extending the QWebView, which is creating a new keyboard widget as a child.
WebView::WebView(QWidget* parent = 0): QWebView(parent)
{
WebPage *page = new WebPage(this);
this->m_keyboard = new widgetKeyBoard(this, Qt::Window|Qt::CustomizeWindowHint);
this->m_keyboard->createKeyboard();
this->m_keyboard->hide();
connect(this, SIGNAL(launchVirtualKB(WebView *) ), SLOT(launchKeyboard(WebView *)));
}
The widgetKeyBoard is made up of QGridLayout with many children QKeyPushButton.
When I do a show of keyboard, I see the whole keyboard drawn briefly and then overwritten 30% of the keyboard from the below web page (overwritten near the input field). I tried to have my own repaint for webview and mainwindow, but still see that someone else is overwriting.
What could be causing such an issue. I am using QT4.8.
What i have is a single dijit.Menu that contains the dijit.MenuItem objects with labels 1 - 9. It is connected to a sudoku like grid of 81 'nodes' (because there are so many, i dont bother with individual id's, i simply collect them with dojo.query('their-css-class-name')). This is the code i'm using inside of a widget to instantiate the context menu and its menu items.
var contextMenu = new dijit.Menu({targetNodeIds:dojo.query(".sudokuNode"), leftClickToOpen:true});
for(var i = 1; i <= 9; i++) {
contextMenu.addChild(new dijit.MenuItem({
label:i,
onClick: function(evt) {
//??
}
}));
};
contextMenu.startup();
What i'm trying to do is have the node that is clicked, and subsequently opens a popup/context menu, be filled with the value (1-9) selected from the context menu's MenuItems.
My problem is that i dont know how to "know" which of the 81 nodes was the one to fire the oncontextmenu event, and i dont know how to reference that node inside the 'onClick' method declared in the menu item.
Any help demonstrating how to reference the calling node in that context would be appreciated! If this isn't enough information, let me know what else i can do to explain my problem!
evt.target should get you the node that was actually clicked. Depending on the structure, you may need to do some other navigation from there, or use dijit.getEnclosingWidget().
If the MenuItems allow the events to bubble (I'm not sure; haven't used it myself), you could connect to the onClick() method of the Menu, so you've only got the single event listener in play.
