Designing simple cell renderer for Nimbus look and feel

由 穿精又带淫゛_ 提交于 2019-12-12 08:56:23
问题 I have a simple-ish cell renderer which is composed of a few JLabel s (the renderer itself extends JPanel ) and I'm trying to get it to render sensibly in the Nimbus look and feel. Basically what is happening is that in the lighter rows (as Nimbus has alternate row coloring ), my specific cell renderer is using the table background color (which is much darker than both lighter and the darker row colors). In my renderer I do: if (isSelected) { setBackground(table.getSelectionBackground); }

Can you set the cells of JTable to spill over?

由 大憨熊 提交于 2019-12-12 01:56:58
问题 I'm trying to imitate some Excel spreadsheet functionality on my JTable, specifically what I've been calling cell spillover or cell overflow. This occurs when you fill a cell with text with a wider width than the cell is set to. If there is no text in the cell to its right, the words simply keep going into the next cell and beyond. I feel like this would be accomplished somehow with TableCellRenderer, but I do not know how. Any help would be much appreciated 回答1: I dont know because you did

Rendering Toedter's JDateChooser in JTable column

问题 Excuses for asking the same question again. I am under the impression that if I added to the original question, I wouldn't get as many views. As I'm using an MVC pattern, my Swing GUI is in a different class with the controller creating an instance of it. Here is how I create the table in my View: tableVehiclePermitHeader = new String[] {"Name", "Expiration Date"}; tableVehiclePermitData = new Object[0][0]; // Calendar tempDate = new GregorianCalendar(2008, 1, 1); // Date tempDate1 = new Date

JTable row color change based on a column value- on pop up click

由 半城伤御伤魂 提交于 2019-12-11 18:05:59
问题 My jtable is loaded with data and this is where I call my Pop up functionality on jTable. jTable.addMouseListener(new TablePopupListener(jTable)); displayTable(); So basically, if I right click a row, a popup(credit check) comes up and if I click it is setting a value to the last cell in that row. Now, based on this column cell value I have to define the color of a row. Let's say, if the cell value is fail then turn the row to red else to green. I have tried customCellRenderer and defined my

Button and Textbox alignment in a jtable cell

由 不打扰是莪最后的温柔 提交于 2019-12-11 06:46:46
问题 I have a table which has both button and text box in some cells. Now I am able to put both the components in the table cell. Thanks for OscarRyz's code. Now my problem is I have to align these components such that the button is to extreme right of the cell and text box should start from the extreme left of the cell to the start of the button. (In simple, they should be adjacent to each other and occupy entire cell.) How can I align them inside the cell? Currently it looks like this, But what
