I'm trying to create jlabels and jtextfields dynamically and add then to a jPanel where the user can insert data into a table in a database.
I retrieve from the database the name of all the table attributes and then I have to create a jlabel and a jtext for each of these names. The result of it should be something like shown below (the label 5 should only be created if there is no more space in the bottom of the jpanel):
I tried to used GroupLayout and SequentialGroup but I couldn't achieve anything similar. I achieved something completely awkward that I can't understand and solve it.
The label called "ESTADO" should be under the "SIGLA" label and the label with the "inserting table is:" text should be in the left hand side of the screen, as in the first image.
My code is:
ArrayList<String[]> tableAtts = sql.getTableAttributeNames(table);
javax.swing.GroupLayout jPDataInsertionLayout = new javax.swing.GroupLayout(jPDataInsertion);
jPDataInsertion.setLayout(jPDataInsertionLayout);
GroupLayout.SequentialGroup shgp = jPDataInsertionLayout.createSequentialGroup();
GroupLayout.SequentialGroup svgp = jPDataInsertionLayout.createSequentialGroup();
jPDataInsertionLayout.setHorizontalGroup(
jPDataInsertionLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.CENTER)
.addGroup(shgp));
jPDataInsertionLayout.setVerticalGroup(
jPDataInsertionLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.CENTER)
.addGroup(svgp));
//shgp.addContainerGap();
svgp.addContainerGap().addComponent(jLInsertingTable);
for (String[] values : tableAtts) {
JLabel jLTableAtt = new JLabel(values[0]);
JTextField jTFTableAtt = new JTextField();
jTFTableAtt.setColumns(13);
shgp.addComponent(true,jLTableAtt)
.addGap(18, 18, 18)
.addComponent(jTFTableAtt, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE);
svgp.addGap(18, 18, 18)
.addGroup(jPDataInsertionLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.BASELINE)
.addComponent(jLTableAtt, javax.swing.GroupLayout.Alignment.BASELINE)
.addComponent(jTFTableAtt,javax.swing.GroupLayout.Alignment.BASELINE ,javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE));
}
shgp.addComponent(jLInsertingTable);
EDIT:
Using what #rcook said, I change the groups and managed to create what I wanted.
Here is the code I manage to create:
ArrayList<String[]> tableAtts = sql.getTableAttributeNames(table);
ArrayList<JLabel> attLabels = new ArrayList<>();
ArrayList<JTextField> attFields = new ArrayList<>();
javax.swing.GroupLayout jPDataInsertionLayout = new javax.swing.GroupLayout(jPDataInsertion);
jPDataInsertion.setLayout(jPDataInsertionLayout);
GroupLayout.SequentialGroup hsg = jPDataInsertionLayout.createSequentialGroup();
ArrayList<String[]> tempTableAtt = new ArrayList<>(tableAtts);
for(int i = 0; (!tempTableAtt.isEmpty()) && i < COLUMN_SIZE ; i++){
GroupLayout.ParallelGroup innerhpg = jPDataInsertionLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.TRAILING, false);
for(int j = 0; (!tempTableAtt.isEmpty()) && j < ROW_SIZE ; j++){
String[] att = tempTableAtt.get(0);
GroupLayout.SequentialGroup innerhsg = jPDataInsertionLayout.createSequentialGroup();
JLabel jLTableAtt = new JLabel(att[0]);
JTextField jTFTableAtt = new JTextField();
jTFTableAtt.setColumns(13);
attLabels.add(jLTableAtt);
attFields.add(jTFTableAtt);
innerhsg.addComponent(jLTableAtt)
.addPreferredGap(javax.swing.LayoutStyle.ComponentPlacement.RELATED)
.addComponent(jTFTableAtt);
innerhpg.addGroup(javax.swing.GroupLayout.Alignment.LEADING, innerhsg);
tempTableAtt.remove(att);
}
hsg.addGap(18,18,18).addGroup(innerhpg);
}
jPDataInsertionLayout.setHorizontalGroup(
jPDataInsertionLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addGroup(jPDataInsertionLayout.createSequentialGroup()
.addContainerGap()
.addGroup(jPDataInsertionLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addComponent(jLInsertingTable)
.addGroup(hsg))));
GroupLayout.SequentialGroup vsg = jPDataInsertionLayout.createSequentialGroup();
vsg.addContainerGap()
.addComponent(jLInsertingTable);
for(int i = 0; i < tableAtts.size() && i < ROW_SIZE; i++){
GroupLayout.ParallelGroup vpg = jPDataInsertionLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.BASELINE);
vpg.addComponent(attLabels.get(i))
.addComponent(attFields.get(i), javax.swing.GroupLayout.PREFERRED_SIZE,javax.swing.GroupLayout.DEFAULT_SIZE,javax.swing.GroupLayout.PREFERRED_SIZE);
for(int j = 0; (tableAtts.size() > ROW_SIZE) && ((i+(ROW_SIZE*(j+1))) < tableAtts.size()) && j < COLUMN_SIZE; j++){
vpg.addComponent(attLabels.get(i+(ROW_SIZE*(j+1))))
.addComponent(attFields.get(i+(ROW_SIZE*(j+1))), javax.swing.GroupLayout.PREFERRED_SIZE,javax.swing.GroupLayout.DEFAULT_SIZE,javax.swing.GroupLayout.PREFERRED_SIZE);
}
vsg.addGap(18, 18, 18).addGroup(vpg);
}
jPDataInsertionLayout.setVerticalGroup(
jPDataInsertionLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addGroup(vsg));
I don't know if that is the best solution but it works.
