java - Converting a variable from Double to Int -

-

Let's say I have variable tmp which is double, and I want to convert the TMP to an integer, But still how would I do this variable named Tmp? Thank you

You do not have the same variables as both int Can be a double .

You may have it though: 

  double D = 0.1d; Int i = (int) d; D = (double); Println (d);

In fact, for the first time you enter your double in a integer , then lose the numerator. Afterwards, you place it on double and specify it in your d variable. You do not have to explicitly cast int to double because it is a comprehensive conversion, but it makes it clear what happens.

The end result is that your d variable is now a value that can be interpreted properly by an integer, but on the other hand, well, basically Your variable threw your variable no to change its type, though.

You can write it like this in a lesser way: 

  double d = (int) 0.1d;

java - How to drag a JavaFX node and detect a drop event outside the JavaFX Windows? -

-
I am implementing a tabkin that can be separated from the JavaFX window. When the tab panel is pulled out of the window where it came from, I have to create a new window and the tab to be placed in that window. I have already applied some methods using drag gestures, drag the tab between the existing window. However, when I'm taking a mouse out of javax sequences, I'm not able to get any mouse events or drag events. Is this something possible? You can listen to a mouse release incident on the appropriate node (like the graphic of the tab). Check the screen coordinates using MouseEvent.getScreenX () and MouseEvent.getScreenY () and see if they are out of the current window. If they do, create a new window, view and tab panel; Remove the tab from the current tab panel and place it in a new location. There is no fundamental example with no frills (for example, a user does not indicate that the dragging is happening), but you should consider this: import Please ...
