JTable标头包含图像，在该图像的顶部，我想在单个标头中放置3个按钮

Question

JTable Header contains Image and on top of that image I want to place 3 buttons in a single header. My requirement is to Create a "Play List" table in which user can add their favourite songs.

So in the header I want to put a "Play List" title and "+" button to insert new playlists and "Export" and "Import" buttons.

How I can do that? Thanks in Advance.

Answer 1

I doubt ⁽¹⁾ this use-case actually calls for cramming extra components into a JTable header. EG Take the UI of DukeBox.

We can see the play list on the left (a JTable ) with a Filter text field and Random check-box above it, and the Enqueue & History buttons below.

This was created with a nested layout. The 'outer layout' is BorderLayout , that panel has the table in the CENTER , and nested panels in the NORTH & SOUTH . The NORTH panel has another BorderLayout , while the SOUTH uses a GridLayout .

If using a nested layout does not give you some ideas, I suggest you post a drawing or better, ASCII art, of the UI as it should appear at the smallest size, as well as a representation of it when it is resized (where is the extra width/height assigned?).

1) I have that suspicion every time I hear words to the effect "Wouldn't it be great if we had a component that..?" . Of course, there are some classic counter-examples where the standard widget tool-kit seems lacking (eg a date picker or switch list), but these are common components to which a name can be put. If the person asking cannot put a 'catchy name' to the custom component, there is a good chance they are over (or under) thinking the matter.
