I'm trying to change the cursor when the user clicks on a column (table header). This seems to only work some of the times, randomly, with no rhyme or reason. Here is my code:
| Code: |  |
dbtResults.getTableHeader().addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent evt) {
setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
try {
Thread.sleep(2000);
} catch (Exception e) {}
setCursor(Cursor.getDefaultCursor());
}
public void mouseReleased(MouseEvent evt) {}
});

mouseClicked() method will be called in EventDispatcherThread, I am not sure what will be the impact of adding a sleep in EventDispatcherThread.
Try to add the cursor change in the following method
DBTableEventListener.onSortColumn(int column, boolean ascending) . This method will be called when user click the column header.

Actually, I'm not supposed to use the Thread.sleep() call in my code. I only put it there to suspend the program long enough to see if the cursor changes or not. The real code should be:
| Code: | |
dbtResults.getTableHeader().addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent evt) {
setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
dbtResults.sortByColumn(2, true);
setCursor(Cursor.getDefaultCursor());
}
public void mouseReleased(MouseEvent evt) {}
});

Basically, I want a "wait" cursor for when the table is sorting, and then to revert to the default cursor when it's done.

Is the mouseclicked method getting invoked when you click the header?
Is it possible the sorting is fast, that the cursor is quickly switched back to default?

Yes, the event is being called but the cursor is not changing. I'm sorting on ~200,000 rows so it actually takes around 3-4 seconds to perform. A client was complaining that they didn't know what was happening when they clicked the header because there was no cursor indication.

Instead of calling dbtable.setCursor, you can get the Jtable used by Quicktable and try to set the cursor.
dbtable.getTable().setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
