Hi,
I would like to display a list of parameters in a power table with 2 columns : Title and Value.
The values have different types, each has a render type and editor type :
- boolean : JCheckbox
- interger : JComboBox
- string : JTextField
I manage to get the desired render with the "configureCell" function
However i can't get the same result with the "configureEditor" Function. It only allows to use one editor per column.
I guess it the event behind :
"jTable.getColumn("xx").setCellEditor(new DefaultCellEditor())"
I found an exemple on the web but i couldn't implement it.
Each Row with different Editor Example
Can someone please help me !!
Thank you.
Maxime.
Do you really need a table for this?
Perhaps you can come a long way with the template repeater. Just make a template that has a label on the left, and various input fields on the right. Show only the correct input field based on the data type, and make sure to pass everything via template parameters.
To get the values back, you can write it to a memory tag.
By adding borders, you can make it look like a real table. There are only a few things you’re missing, like f.e. resizing columns.
This is an example of what I made with the template repeater. The keys are for a label, and are extracted from a label template. The values are user-editable.
Maybe you are right. I hesitated with this solution.
However, I managed to do something nice with a power table.
I only have one problem left : i Have None in “newValue” in event “onCellEdit”.
My code for “configEditor”
from javax.swing import DefaultCellEditor
from javax.swing import DefaultComboBoxModel
from javax.swing import JTextField
from javax.swing import JComboBox
from javax.swing import JCheckBox
if colName == "val":
root = self
class CustomCellEditor(DefaultCellEditor):
def getTableCellEditorComponent(self, table, value, isSelected, row, column):
#get powertable.data
pydata = system.dataset.toPyDataSet(root.data)
#get type (in another column)
type = pydata[row]["type"]
#get column value
val = pydata[row]["val"]
#type boolean
if type == "boolean":
#cast string in bool
checkboxValue = val in ['true', '1', 'True']
dce = DefaultCellEditor(JCheckBox())
comp = dce.getTableCellEditorComponent(table, value, isSelected, row, column)
# set selected value
comp.setSelected(checkboxValue)
return comp
#type combo box
elif type == "combo":
dce = DefaultCellEditor(JComboBox())
comp = dce.getTableCellEditorComponent(table, value, isSelected, row, column)
dataFullText = []
#get powertable.options (custom property of power table, type : dataset, list of combobox options)
data = []
...
#code for make list of combobox options
...
comp.setModel(DefaultComboBoxModel(data))
selectedText = ""
...
#code for get item to select
...
#set selected value
comp.setSelectedItem(selectedText)
return comp
retour = CustomCellEditor(JComboBox())
return {'editor': retour}
I tried to rewrite the property getCellEditorValue () but without success.
I have an error : “getCellEditorValue() takes no arguments (1 given)”.
I think that in python there is a first argument, even if it is not declared : “self”
With “@staticmethod” it’s work better !!!
I managed to do what I wanted. I’m so happy !!
I’m trying to do exactly the same. Where are you putting @staticmethod to get newValue to return the edited value?
Finally I used a repeater template as sanderd17 said. It’s simpler, no need to master Java and more flexible.
It’s heavy and not perfect. There are problems during the validation, etc …
Otherwise here is the code with the static function:

from javax.swing import DefaultComboBoxModel
from javax.swing import JTextField
from javax.swing import JComboBox
from javax.swing import JCheckBox
from javax.swing import JSpinner

That worked a treat! Merci beaucoup.
