I am trying to build a chrome extension. In it I want the context menu to change according to the selected text on the page.
For example, if its a number I want a menu that says divisibility test for this numbr is ...
and if it is a string, it should have a something else, but not both at the same time.
I cant figure out how to do that.
You will have to set a listener for mouse down. There is no other way to get the selected text before the menu is created.
See this SO question:
chrome extension context menus, how to display a menu item only when there is no selection?
Here is part of the code the rest is at the link.
document.addEventListener("mousedown", function(event){
//right click
if(event.button == 2) {
if(window.getSelection().toString()) {
chrome.extension.sendRequest({cmd: "createSelectionMenu"});
} else {
chrome.extension.sendRequest({cmd: "createRegularMenu"});
}
}
}, true);

I'm integrating GoogleCast to my app. Its root view controller is a UITabBarController, with a custom white tab bar.
After I wrapped it with a GCKUICastContainerViewController, the Home Indicator background area became black (and the indicator is white).
How can I make this Container VC extend its child VC (my tab bar controller) below the home indicator?
Note: There is an ugly workaround that I tried, which is to set castContainerVC.view.backgroundColor = .white. This would work if the tab bar was always visible, but some parts of my navigation stack may choose to hide it. When it happens, I'd end with a white Home Indicator area, but whatever color the presented view controller has above the indicator.
extension GCKUICastContainerViewController {
open override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
if let window = UIApplication.shared.keyWindow, miniMediaControlsViewController?.view.bounds.height ?? 0 == 0 {
contentViewController?.view.frame = window.frame
} else {
contentViewController?.view.frame = (view.subviews.first! as UIView).frame
}
}
}
Yes, it appears Google wants us to have the GCKUICastContainerViewController as the root view controller. And it looks like it has some layout issue when there is safe area inset at the bottom of the display.
I solved this by changing the view's frame manually in viewDidLayoutSubviews. You can do it with an extension like this
extension GCKUICastContainerViewController {
open override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
if let window = UIApplication.shared.keyWindow {
contentViewController?.view.frame = window.frame
}
}
}
This way you will get rid of the space at the bottom of the screen. Works for me.
I developed an app using Xamarin forms that has side menu see this url.
But I couldn't use this in my current project, so I made my custom component for side menu.
How to implementing feature that hide menu when I tap range out of side menu?
It is hard to give you any help without seeing your code, but generally I tackle this issue by adding a ContentView that covers the screen when ever your menu opens. The menu would be displayed on top of the ContentView. Then you add a TapGestureRecognizer to the ContentView which closes the menu when clicked.
You could add some color to the ContentView but make it opaque so it is see-through, something like this color: #74787878
ContentView backgroundView = new ContentView {
BackgroundColor = Color.FromHex("#74787878"),
HorizontalOptions = LayoutOptions.FillAndExpand,
VerticalOptions = LayoutOptions.FillAndExpand,
Content = //Your menu
}
backgroundView.GestureRecognizers.Add(new TapGestureRecognizer {
Command = new Command(() => {
//Remove the background and hide the menu
})
});
Assume that there are many tabs are there in p:tabview and scroll is being shown to navigate to all the tabs.
If the active tab whose contents are shown is the right most tab then it is not visible to the user on initial p:tabview load. If we navigate to the right most using scroll button then we could see the active tab highlighted indicating it is selected tab.
How to scroll to the active tab on load so that user able to see the selected tab always.
This can be done in the following way by overriding initScrolling method in primefaces p:tabview component JavaScript file i.e. tabview.js file.
initScrolling: function() {
if(this.jq.is(':visible')) {
var overflown = (this.lastTab.position().left - this.firstTab.position().left) >
this.navscroller.innerWidth();
if(overflown) {
this.navscroller.css('padding-left', '18px');
this.navcrollerLeft.show();
this.navcrollerRight.show();
activeTab = this.navContainer.children('.ui-tabs-selected');
viewportWidth = this.navscroller.innerWidth();
activeTabPosition = activeTab.position().left + parseInt(activeTab.innerWidth());
if(activeTabPosition > viewportWidth) {
var scrollStep = activeTabPosition - viewportWidth;
scrollStep = Math.ceil(scrollStep/100) * -100;
this.scroll(scrollStep);
} else {
this.restoreScrollState();
}
}
return true;
}
else {
return false;
}
}
I would have wished to override this single method by extending tabview component widget but it is not supported. So we should have our own tabview.js file with the above method modified.
This is done in primefaces 4.0 version, more, or less the changes will be same higher versions also.
I would like to be able to link to individual tabs in a PrimeFaces' "tabView". In other words, if my page "test.jsf" has a tabView with a tab entitled "Example", I want to be able to click a link to "Test.jsf#Example" and have the "Example" tab loaded automatically. How can I do this?
This can be done with a wee bit of JavaScript (using jQuery). I hope I have commented the following code well-enough that it can be understood.
<script type="text/javascript">
// What this does: when the page is loaded with a URL fragment (i.e, the #abc in example.com/index.html#abc),
// load the tab (by "clicking" on the link) that has the same text value as the fragment.
// Example: if you go to test.jsf#Example, the tab called "Example" will be clicked and loaded.
// This allows individual tabs to be linked to, and puts what tab you were on in the history.
navigateToTab = function () {
if (window.location.hash) {
jQuery('ul.ui-tabs-nav li a').each(function (i, el) {
if (jQuery(el).text() === window.location.hash.replace('#', '')) {
jQuery(el).click();
return;
}
})
}
};
jQuery().ready(navigateToTab);
jQuery(window).bind('hashchange', navigateToTab);
// This makes it so that if you click a tab, it sets the URL fragment to be the tab's title. See above.
// E.g. if you click on the tab called "Example", then it sets the onclick attribute of the tab's "a" tag
// to be "#Example"
setupTabFragmentLinks = function () {
jQuery('ul.ui-tabs-nav li a').each(function (i, el) {
el.onclick = function() {window.location = '#' + jQuery(el).text()};
})
};
jQuery().ready(setupTabFragmentLinks);
</script>
All you have to do is insert that JavaScript in the page that has the tabs. Then you can get a link to a tab with the usual <a href='test.jsf#Example>Click here!</a>. An added bonus is that the tab you were on becomes part of the browser history; i.e., if you navigate away from the page that has the tabs, then press the "back" button, you are brought back to the tab you were on.
Note: if the tabView changes (e.g. you add or remove tabs), you will need to call setupTabFragmentLinks again.
Primefaces provides a javascript API for the <p:tabView/>(and many other components). You can call the select(index) method on the client side widgetVar name of your <p:tabView/>. For example, on a tab view
<p:tabView id="thePanel" widgetVar="tabPanel"/>
From a <p:CommandButton/>, you can call tabPanel.select(1) in the onclick attribute to select the first tab and so forth
<p:commandButton update=":thePanel" value="Do It " id="doIt" onclick="tabPanel.select(1)"/>
I would like to have a qtip2 tooltip without a title bar, but with a close icon in the corner. Is there a way to spec that, or do I have to muck with the code that creates it? I am thinking of something that floats the button to the left or to the right, allowing the rest of the content to fill the tooltip div.
Always keep the close markup separately and update with your current qTip Text.
$('.selector').qtip({
content: {
text: function(api) {
var qTipContent = $('.close-markup').html();
qTipContent += $('.qtip-content').html();
return $('.qtip-content').html();
}
}
});
$('.close-markup').qtip('destroy');
Try the above code.
Note: Does not require to muck the qTip Close code snippet!
