Strange Spinner. How to fix it?
(4 answers)
Closed 8 years ago.
I have spinner and code android.R.layout.simple_spinner_dropdown_item.
But I get weird height like this:
I want to have dropdown_items like they are by default but also I don't want to have weird height on the main screen.
Use the adapter.setDropDownViewResource(int resId) method to use a specific layout for the dropdown box (not the elements)

FXMLLoader how to access the components by FXID?

So i am a beginner programmer and
what I'm trying to do is to get specific button's text by knowing its fx:id
Is it possible?
For example if button fx:id = "buttonOne" and text = "X"
how can I get X?
You can define your button in controller (fx:id should be equals name of the field):
#FXML
Button buttonOne;
And just use getText():
buttonOne.getText();

How to setEnabled() in javafx-8?

I'm working with JavaFX. I have a disabled TextField.
private TextField numberField;
How can I make the TextField enable/editable?
I have used:
numberField.setVisible(true);
But it's not working.
You can use
numberField.setEditable(true)
numberField.setDisable(false)
setEditable(true) will actually make numberField edible and setDisable(false) will make sure numberField is not greyed out.
As the name suggests, setVisible(boolean) will only make the object visible/invisible.
setVisible(boolean) is used to change visible property but for your case you need those two:
numberField.setEditable(true);
numberField.setDisable(false);

How to go back to a JFrames in Java

Closed 7 years ago.
When I open a new JFrame, I set the old one as false:
ExampleJFrame.this.setVisible(false);
ExampleNewJframe newOne = ExampleNewJframe();
newOne.setVisible(true);
But If I am in newOne, how do I get back to the original Frame without creating a new as I did above?
The best solution: don't go swapping JFrames; that's can be a rough design that can annoy users. Instead swap JPanel "views" using a CardLayout as per The Use of Multiple JFrames, Good/Bad Practice?.

I have taken one JFrame in which we have shown the information about our firm
there is one information(label) like:
website: www.samteksystems.com
I want that whenever I click on www.samteksystems.com it should display that website.
Please help me in this.
You can add a mouseListener to the label, and in the mouseReleased() method, you could use Desktop.browse() to visit the URL.
