html - Explore style element in GWT client code -

-

I have a GWT code that creates a list (as a result grid) and I have a style like a CSS class

.test tr {height: 26px; }

Now ... if the code requires me to get "26px" when the render is not complete or when there is no element in the grid? Can I get that value? I know I can 

  obj.getElement (). GetStyle () GetProperty ("height");

How to get some style attributes, but how can I get sub-element tr related values?

style property, - It does not automatically pick up CSS that it has been applied to, or CSS has been applied to parent nodes and it has been inherited, etc.

To do this, you need to get the 'calculated' style of the element. This is some expensive operation, so should be done carefully, and will not work in earlier versions of IE, so A completely different code should be written. Some libraries like GSTT have a built-in feature for you to do this ( XElement.getComputedStyle (...) ), if you are not using a library like this, then you write JSNI Who can call this API and ask for these details.

Check (Use IE8 and not below, old Android browser and Opera Mini have a problem), and for details of call in your JSN, using $ wnd Refer to the window object for something like this: 

  $ wnd.getComputedStyle (element) .getPropertyValue ('height');

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 ...
