cellrenderer

I am currently trying to disable the selectable / editable / or change the textInput to dynamic to get my desired result. I've got a custom datagrid with dropdowns and text input areas. However, if there is no data in my Model # column, I do not want to allow for any entry in the corresponding PurchasePrice cell. col1 = new DataGridColumn("Model"); col1.headerText = "Model #"; c2.consumables_dg.addColumn(col1); col1.width = 60; col1.editable = false; col1.sortable = false; col1.cellRenderer = AlternatingRowColors_editNum_PurchasePrice; col1 = new DataGridColumn("PurchasePrice"); col1

I am trying to limit the amount of decimal places shown in a Gtk.CellRendererText. Currently a float number field is shown with 6 decimal places, but I would like to have just 1. This test code should work on Linux: #!/usr/bin/python3 from gi.repository import Gtk class MyWindow(Gtk.Window): def __init__(self): Gtk.Window.__init__(self, title="Hello World") self.set_default_size(200, 200) self.liststore = Gtk.ListStore(float) treeview = Gtk.TreeView(model=self.liststore) self.liststore.append([9.9]) self.liststore.append([1]) xrenderer = Gtk.CellRendererText() xrenderer.set_property("editable"

I noticed this is common. For example DefaultListCellRenderer, DefaultTableCellRenderer, and DefaultTreeCellRenderer all use it. Also a lot of the custom cell renderers I see online use this as well. I want to use a custom TableCellRenderer in my code, but I'm confused about whether I really need to subclass JLabel. What's the benefit of subclassing JLabel? camickr The API for the DefaultTableCellRenderer states: The table class defines a single cell renderer and uses it as a as a rubber-stamp for rendering all cells in the table; it renders the first cell, changes the contents of that cell

I am using a JTable in my GUI application as a grid to represent positions for a game. I want the cells of the table that represent a certain position of an object to have a certain color, and on some actions, the object to move (i.e the color cell to move around in the Grid /JTable). I know that I can change cell colors by making a class that extends DefaultTableCellRenderer , is this the only way it can be done? or is there a simpler way to chage cell colors??Also Is JXTable better than JTable for such an application ? EDIT: I didn't include the fact that I need certain cell colors to change

I'm trying to render an specific row of my jtable (it should have a different background color and it should have bold characters). I found several questions regarding how to implement a custom TableCellRenderer ( here and here ) and the tutorial How to Use Tables and this one ( Table Row Rendering ). I'm using a JInternalFrame to display the JTable . I tried to implement both solutions but neither getCellRenderer nor prepareRenderer are being called. When debugging, I can see my new jtable being created, but, my breakpoint inside the methods aren't called. My code looks like: this.add

So I know this may be a duplicate question, but I've looked through many of the ones already on here and none of them seem to work for me, so I thought I would post my own and hopefully some of the other people having trouble with this will find this helpful also. Here is my code table.getColumn("Name").setCellRenderer( new DefaultTableCellRenderer() { @Override public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { setText(value.toString()); if (row==3) { setForeground(Color.RED); } return this; } } ); Here is
