Cell validation in JTable

由 纵然是瞬间 提交于 2019-11-27 07:04:00
问题 I have a JTable that needs cell validation for the cells where the user can input text. When a user enters invalid text the border of the cell turns red. I've managed to get this working associating a two dimension array to flag if each cell has errors or not. The problem is that the user must be able to reorder the table (by column). I have to store the error flag in the table model, not separatly. Anyone has ideas how to do this? 回答1: Also consider a custom TableCellEditor , seen here and

I'm working in a project in which we have several domain classes to model business data. Those classes are simple POJO's and I have to display several tables using them. For example, consider this class: public class Customer { private Long id; private Date entryDate; private String name; private String address; private String phoneNumber; public Customer(Long id, Date entryDate, String name, String address, String phoneNumber) { this.id = id; this.entryDate = entryDate; this.nombre = name; this.domicilio = address; this.telefono = phoneNumber; } // Getters and setters here } I have created

Mass produce JTables

问题 I want to make 25 JTables. I generate the table names by doing: for(int i=0; i < 26; i++) { TableNames[i] = "Table" + i + ""; ... How can I go about using these String names in the array as the new JTable names? i.e. TableNames[i] = new JTable(model){ ... 回答1: Instead of an array, consider using a List<JTable> or List<TableModel> . Pass the name to the table's constructor or factory method. The example below uses the Component 's name, but a JComponent 's client property may be more versatile

Java, change a cell content as a function of another cell in the same row

I need some help for my problem. I have a table with e.g. a double column and a string column. If the value in the double column is negativ, the string should be "negativ". And the other way if the value is positiv, the string should be "positiv". The problem is now if I edit the double value in the jTable, the string should also be updated. Update to my question, the actual code look like this: But it doesn't work, because the string in the second column wont be updated after I edit the first column value. It only works when I start the program the first time. import java.util.Vector; import

How to implement dynamic GUI in swing

由 两盒软妹~` 提交于 2019-11-26 11:52:26
First of all, apologies for posting something perhaps a bit excessively specific, but I'm not very experienced with Swing, and can't seem to find good examples that fit my needs. So I'm trying to figure out the best way to implement the a dynamic GUI for choosing filtering criteria in Swing: The underlying model is a class containing a list of criteria that can be negated (i.e. applied with a NOT-prefix), and a property indicating whether these should be combined with AND or OR. The GUI would allow the user to add, change or remove criteria, and select the combination operator (and/or). The
