In this part bahamas construction jobs the Java Swing tutorial, we are going to work with menus and toolbars. In the examples we will create regular menus, submenus, checbox menu items, radio button menu items, popup menus, and toolbars. A menu is a group of commands located in a menubar. A toolbar has buttons with some common commands in the application. Our example will show a menu with one item. Selecting the Exit menu item we close the application.
A menu object is created with the JMenu class. The menus can be accessed via keyboard as well. To bind a menu to a particular key, we use the setMnemonic method. A menu object consists of menu items. A menu item is created with the JMenuItem class. A menu item has its own mnemonic. JMenuItem is a special kind of a button component. We add an action listener to it, which terminates the application.
Each menu can also have a submenu. This way we can put similar commands into groups. For example, we can place commands that hide and show various toolbars like personal bar, address bar, status bar or navigation bar into a submenu called toolbars. Within a menu, we can separate commands with a separator. The separator is a simple line. It is common practice to separate commands like New, Open, Save from commands like Print, Print preview with a single separator.
How to show a context menu
In addition to mnemonics, menu commands can be launched via accelerators. A submenu is just like any other normal menu. It is created the same way. We simply add a menu to existing menu. A separator is a horizontal line that visually separates menu items. This way we can group items into some logical places. A separator is created with the addSeparator method.
Mnemonics and accelerators are shortcut keys that enable executing commands via keyboard. Mnemonics navigate the menu hierarchy to select a specific menu item whereas accelerators bypass menu hierarchy and directly activate the menu item.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.
If nothing happens, download GitHub Desktop and try again. If nothing happens, download Xcode and try again. If nothing happens, download the GitHub extension for Visual Studio and try again. This version is Swift 5 compatible. For the Swift 4. PopupDialog is available through CocoaPods.
Simply add the following to your Podfile:. Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. A minimum version of 0. If you prefer not to use either of the above mentioned dependency managers, you can integrate PopupDialog into your project manually by adding the files contained in the Classes folder to your project. Moreover, you have to manually add the classes of DynamicBlurView to your project. You can find this and more example projects in the repo.
To run it, clone the repo, and run pod install from the Example directory first. PopupDialog is a subclass of UIViewController and as such can be added to your view controller modally. You can initialize it either with the handy default view or a custom view controller.
The default dialog initializer is a convenient way of creating a popup with image, title and message see image one and three. Bascially, all parameters are optional, although this makes no sense at all. You want to at least add a message and a single button, otherwise the dialog can't be dismissed, unless you do it manually. The ratio of the image will be used to set the height of the image view, so no distortion will occur.
You can pass your own view controller to PopupDialog see image two. It is accessible via the viewController property of PopupDialog, which has to be casted to your view controllers class to access its properties. Make sure the custom view defines all constraints needed, so you don't run into any autolayout issues.
Buttons are added below the controllers view, however, these buttons are optional. If you decide to not add any buttons, you have to take care of dismissing the dialog manually. Buttons can be distributed either. Please note distributing buttons horizontally might not be a good idea if you have more than two buttons.
You can set a transition animation style with. The following transition styles are available. PopupDialog will always try to have a max width of On iPhones with smaller screens, like iPhone 5 SE, width would be By setting preferredWidth you can override the max width of for iPads only.
Gesture dismissal allows your dialog being dismissed either by a background tap or by swiping the dialog down. By default, this is set to true. You can prevent this behavior by setting either tapGestureDismissal or panGestureDismissal to false in the initializer. PopupDialog can hide the status bar whenever it is displayed. Defaults to false. This completion handler is called when the dialog was dismissed. This is especially useful for catching a gesture dismissal.A pop-up button often referred to as a pop-up menu is a type of button that, when clicked, displays a menu containing a list of mutually exclusive choices.
A pop-up button includes a double-arrow indicator that alludes to the direction in which the menu will appear. The menu appears on top of the button.
After the menu is revealed, it remains open until the user chooses a menu item, clicks outside of the menu, switches to another app, or quits the app; or until the system displays an alert. In general, use a label to introduce a pop-up button.
Create labels with sentence-style capitalization, ending with a colon. Use a pop-up button to present a list of things or states, not commands.
How to Use Menus
If you need to provide a list of commands, use a pull-down button instead. See Pull-Down Buttons. Display a reasonable default selection.
When closed, a pop-up button displays the selected item. Restrict the menu of a pop-up button to a single level. Submenus hide choices too deeply and are difficult to navigate. Use a pop-up button to present a static list of mutually exclusive options. If you need to offer a list of commands or let people choose multiple states, use a pull-down button instead. Consider using a pop-up button as an alternative to other types of selection controls. For example, if you have a dialog that contains a set of six or more radio buttons, you might consider replacing them with a single pop-up button to save space.
Use checkboxes or a pull-down button instead of a pop-up button to allow multiple selections. Apply the appropriate style when using a pop-up button in a toolbar. Use the textured, rounded style. For related guidance, see Toolbars. If your pop-up button requires similar customization options, put them at the bottom of the menu below a separator line.
Try to make multiple stacked pop-up buttons the same width within a view.
Even if the visible contents of each pop-up button varies, the width of the controls themselves should ideally be equal. For related guidance, see Menu Anatomy.
Pop-Up Buttons A pop-up button often referred to as a pop-up menu is a type of button that, when clicked, displays a menu containing a list of mutually exclusive choices. Pop-up button Pop-up button menu In general, use a label to introduce a pop-up button.But this approach had a few weaknesses:. Nowadays, I usually recommend using a Tab Bar Controller instead of a slide-out menu.
It takes a while to get used to Custom View Controller Transitions. Download the starter project zip file. You can tap the buttons in the corners to open and close the modal. This tutorial only uses. Right for opening the menu, and. Left for closing it. This method calculates the progress in a particular direction. For example, if you specify the. Left tracks progress in the negative-x direction. Currently, the menu modal opens using the default slide-up animation.
We want to override this with a custom animation where the main content slides-right to reveal the menu underneath. Before your custom animation will start working, you need to wire it up. Replace MainViewController. But this is actually a good thing. Within the Storyboard, find the MenuViewController scene green.
As usual, the animation begins with the ContainerView and the fromVC.
Fun Is Fast
To see the dismiss animator in action, wire it up to the appropriate transitioning delegate method. Build and run. The closing animation should now slide the main content area back to its original position. As the user drags horizontally, the dismiss animation will scrub to its corresponding progress point. All of this code is essentially trying to update the transition status each time a pan gesture event is fired. This makes the snapshot feel like a real object.

I'm doing some drawing on a custom UIView canvas, and rather than having a set of buttons at the bottom of the view to allow the user to select shapes, I'd like to have the user do a long press gesture, then have a popup-type menu appear with different shapes they can choose.
I don't see anything like this in xCode, though I'd assume there's something like that in iOS. I don't want the alert popup that shows up when you have low battery and notifications. I've looked into using a UIPopoverController but I'm a bit confused about some of the other Stack Overflow questions I've read about it, and also about the documentation given by Apple. In my case I am returning CGSize with width and size You can set these values so as to fit your floating menu content properly.
After you make a connection of that button with the viewController and popover as a segue you will need to prepare. Here is the following code in order to prepare for the popover segue.
Do keep in mind that if you have an iPhone the popover will take full screen, so you can fix that using this for let's say a text that takes some particular elements. I have those 2 in different view controllers but I guess it will work. I used Masture's method above and it worked for me thank you!
Make sure you put "ShowMenuSegue" or whatever you choose as the identifier for your segue in the Storyboard, and. Learn more. Asked 5 years, 4 months ago. Active 6 months ago. Viewed 9k times.

Sign up using Email and Password.Navigation is an important part of every user interface. The sidebar menu that we discussed in the earlier tutorial is an example. Slide down menu is another common menu design. When a user taps the menu button, the main screen slides down to reveal the menu. If you have no idea about how a slide-down menu works, no worries. Before showing you how to implement the menu, this tutorial assumes that you have a basic understanding of custom view controller transition.
For those who are new to view controller transition, you can check out this beginner tutorial written by Joyce. In this tutorial, we will build a slide down menu in Swift. You can download the project template here. It includes the storyboard and view controller classes. You will find two table view controllers. One is for the main screen embedded in a navigation controller and the other is for the navigation menu.
If you run the project, the app should present you the main interface with some dummy data. Before moving on, take a few minutes to browse through the code template to familiarize yourself with the project.
First, open the Main.
You should find two table view controllers, which are not connected with any segue yet. In order to bring up the menu when a user taps the menu button, control-drag from the menu button to the menu table view controller.
If you run the project now, the menu will be presented as a modal view. In order to dismiss the menu, we will add an unwind segue. Next, go to the storyboard. Control-drag from the prototype cell of the Menu table view controller to the exit icon. When prompted, select the unwindToHome: option under selection segue. Now when a user taps any menu item, the menu controller will dismiss to reveal the main screen.
Through the unwindToHome: action method, the main view controller i. NewsTableViewController retrieves the menu item selected by the user and changes its title accordingly. To keep things simple, we just change the title of the navigation bar and will not alter the content of the main screen.
In addition, the menu controller will highlight the currently selected item in white. There are a couple of methods we need to implement before the app can work as expected. In the NewsTableViewController. Now compile and run the project. Tap the menu item and the app will present you the menu modally. When you select a menu item, the menu will dismiss and the navigation bar title will change accordingly.
When a user taps the menu, the main view begins to slide down until it reaches the predefined location, which is points away from the bottom of the screen. The below illustration should give you a better idea of the sliding menu.
To create the slide down effect, we will create a slide down animator called MenuTransitionManager.A multi-stage party that brings together the entire run community. Login Create Account Download.
