Using values from a for loop in a function outside of it

由 两盒软妹~` 提交于 2019-12-11 05:30:08
问题 I need to take values that I find from inside a for loop to use in a function that isn't inside the loop, and I can't figure out how to do this. What I am hoping to accomplish is to extract values from a key in a hashmap to then plot in a JTable only if that row is selected (using a ListSelectionListener ). This way, I can avoid graphing a hundred tables which would save a lot of time. Also I am using DefaultTableModel . This is my for loop: tableMaker(model); for(Map.Entry<String

JTable cell listener?

由 大憨熊 提交于 2019-12-06 19:10:53
问题 I am using a JTable. I need to get a notification whenever a cell selection change. I tried to use the ListSelectionListener but I only get notification when the row selection change. If I select a new column on the same row, I don't get notify. I need to know when the cell is selected, not when the cell is changed. Is there a listener that I can use to do this ? 回答1: The easiest way to do this is to call setCellSelectionEnabled(true) , and pass a reference to your table to the listener. When

问题 Is there any way to use ListSelectionListener or MouseAdapter to get information about selected value (if value is a String for example), is there any built-in method for that?

Selecting a row on a JTable shall automatically select the corresponding row on another table, but it does not work

I have a problem with the selection of rows on my JTable instances. This is what I would like to to: I want to have two equal tables with the same data in the rows. When you select a row on the first table, e g the third row, I also want the third row on the second table to be selected automatically. I have solved this by adding a ListSelectionListener to the JTable that updates a class that just hold the selected value. Then that class triggers the other JTable with the selected value from the first. What my problem is: My problem occurs when the user sorts the rows on one of the tables. Then
