回答1:

Open NetBeans and choose Window -> Palette It will appear but it will be empty because you didn't choose a GUI class yet.

To fill the palette with the GUI components like labels, follow these steps:

1. Create a new project .

2. Right click in the package name or project name, and choose New -> Other...

3. In the New File dialog box, choose the "Swing GUI Forms" from category and the "JFrame" Form file type sub window. Click Next.

4. Enter name lets say "MyGUI" for the new the class which you created now.

5. The palette window is now full with components like labels, text,checkboxes, ...

if not appear yet make sure to press "Design" button in the upper of the GUI class bar "MyGUI"class

I think the same problem occur here.Check this solution.it may helpful to you.

This steps for restore the default palette?

1. Exit the IDE.
2. Go to your user directory and go down to config/Palette subdir. In this directory, the files or directories deleted from the default palette content are presented as empty files with _hidden suffix in their names.
3. Delete these _hidden files to let the palette categories and items appear again in the IDE.

I think this will help you

回答4:

Do one thing, simply right click on your netbeans project and then open it. It resolves the problem. You will observe if u open a new project the palette is there, so just copy the project with a different name, its will solve your problem.

回答5:

In my case after creating a new project without a default constructor, the search box at the palette holds a single character i.e. '='. this results in an empty palette too.

In that case the solution is obvious: just delete the content of the search input. It puzzled me for a moment, though, not noticing the search input field content.

回答6:

I had the same situation with my netbeans. The only solution I did was to backup my project folder (saving it to other drive). Then re-install the netbeans. Afterwards I re-paste the project folder at the directory and re-open it.

回答7:

Right-click mouse button at palette box. Choose command "reset palette".

回答8:

I encountered the same problem. Just check the bottom of the palette to see if there is a search box open. If there is, close it. Then the palette will be available once again.
