问题 So recently I was working on an a tool for us here to configure certain applications. It didn't need to be anything really awesome, just a basic tool with some SQL script generation, and creating a couple of XML files. During this I created a series of JTable objects with my own implementation of the AbstractTableModel. After I had built everything, and got to the point where I was testing saving and loading using the AbstractTableModel (just written to disk using the ObjectStreamWriter)

问题 I´m trying to implement an undo (and redo) function for an editable JTable with the default components. The JTable has an extra class to specify its properties called SpecifiedJTable . To do so I wanted to grab the moment when a cell is doubleclicked (i.e. the moment when a cell is chosen/marked to be edited) to push the information in the cell and its coordinates onto the stack. This should be done by a MouseListener ...at least that was my idea. I tried this (standing in the constructor of

问题 I have JTabbedPane with many generated dynamically JPanels, that contains JTable. How can i get/set JTable from the selected JTabbedPane tab?

问题 You can go into a cell in a Jtable either by clicking on it, or by going into it using cursor keys/tabs. With defaultCellEditor and a JtextField if you go in using cursor keys the caret is put at the end of the existing text field, whereas if you double click the field it will highlight the last word.

问题 I have a JTable set on SINGLE_SELECTION mode, i.e. the user can only select one row at a time. I am trying to override the CTRL + C KeyListener so that it will copy the whole table to the clipboard. At the moment, I have added a KeyListener to the JTable itself in its constructor: public MyTable(AbstractTableModel model) { super(model); getSelectionModel().setSelectionMode(ListSelectionModel.SINGLE_SELECTION); addKeyListener(new ExcelClipboardKeyAdapter(this)); } The KeyListener looks like

问题 Hi if You put JComboBox in JTable and String[] array to JComboBox everything works fine. Buf if You put your own data type to JComboBox selecting values in same column becomes complicated.
