Use the annotation -- @FixMethodOrder(MethodSorters.DEFAULT). This runs all tests within the class in a deterministic and somewhat predictable order. The implementation hashes the method names and compares them. In the scenario of a tie, it sorts by lexicographical order. Code Segment Below Taken f...
Use the annotation @FixMethodOrder with the method sorter MethodSorters.NAME_ASCENDING. This will run all tests within the class in a deterministic and predictable order. The implementation compares the method names and in the case of a tie, it compares the methods' toString(). Code Segment Below T...
Radio Buttons allow you to let the user choose one element of those given. There are two ways to declare a RadioButton with a text besides it. Either by using the default constructor RadioButton() and setting the text with the setText(String) method or by using the other constructor RadioButton(Stri...
A ToggleGroup is used to manage the RadioButtons so that just one in each group can be selected at each time. Create a simple ToggleGroup like following: ToggleGroup group = new ToggleGroup(); After creating a Togglegroup it can be assigned to the RadioButtons by using setToggleGroup(ToggleGrou...
Typically, when one of the RadioButtons in a ToggleGroup is selected the application performs an action. Below is an example which prints the user data of the selected RadioButton which has been set with setUserData(Object). radioButton1.setUserData("awesome") radioButton2.setUserData(&q...
Let's say the second RadioButton out of three is pre-selected with setSelected(Boolean), the focus is still at the first RadioButton by default. To change this use the requestFocus() method. radioButton2.setSelected(true); radioButton2.requestFocus();
Sometimes we need a visual hint to indicate the return status of previous command. The following snippet make put it at the head of the PS1. Note that the __stat() function should be called every time a new PS1 is generated, or else it would stick to the return status of last command of your .bashr...
Open Storyboard where you have your ViewController with TableView: Add prototype cell (if there is no cell added before): Customize cell as you want (in my case there is custom UIImage and Label): Remember to set height of the cell. To do it select your whole TableView and from the Properties...

While each mobile platforms do offer their own settings management api, there are no built in ways to read settings from a good old .net style app.config xml file; This is due to a bunch of good reasons, notably the .net framework configuration management api being on the heavyweight side, and each...
Express passes a next callback to every route handler and middleware function that can be used to break logic for single routes across multiple handlers. Calling next() with no arguments tells express to continue to the next matching middleware or route handler. Calling next(err) with an error will ...

We use the following media queries in our Less files to create the key breakpoints in our grid system. /* Extra small devices (phones, less than 768px) */ /* No media query since this is the default in Bootstrap */ /* Small devices (tablets, 768px and up) */ @media (min-width: @screen-sm-min) ...
