renderer

I'm trying to use Scala/Swing to create a Table, one of whose columns is populated by Button s. My starting point is the SCells spreadsheet example from Odersky et al's book , and in particular the use of rendererComponent to control the Component appearing in each cell. Unfortunately, while this creates a button successfully, the button is not clickable. Here's a reasonably minimal and self-contained example: import swing._ import swing.event._ class TableButtons extends ScrollPane { viewportView = new Table(2,2) { rowHeight = 25 override def rendererComponent(isSelected: Boolean, hasFocus:

I like the ToolStripProfessionalRenderer style quite a lot, but I do not like the way it renders a ToolStripTextBox. Here, ToolStripSystemRenderer does a better job IMO. Now is there a way to combine both renderers' behaviour to use system style for text boxes and pro style for everything else? I have successfully managed to use pro style for buttons and system style for the rest (by deriving both classes). But text boxes in a ToolStrip don't seem to be handled by the renderer. Using .NET Reflector, those text boxes don't even seem to have a Paint event handler, although it's called by the

Our idea was to draw a waterfall chart with unregular widths. We achieved this chart style by rendering rectangulars to the corresponding data points (visible in fiddle for demonstration purposes). Moreover, we want to add a tooltip and make this tooltip following the mouse. We are facing three problems: When you zoom very close to the chart, you will see that namely rect2 and rect3 as well as rect3 and rect4 show small gaps between the rectangulars edges. This seems to be strange because all rectangulars have been created by the same for-loop procedure (lines 68-84 in fiddle). Any ideas? (If

Widgets in JTable columns are expected to be not distinguishable from normal ones, right? There seems to be behavioral difference, take Swing documentation example and move mouse over checkboxes in the Vegetarian column... They don't react at all. I understand that those are just widget surrogates, so highlighting has to be done manually, so how would I fix this? I tried widget.requestFocusInWindow(); in mouseMoved() for the surrogate widget event handler without success. Any other workaround? You can create your own cell renderer that applies a rollover effect. Then, add a mouse listener that

Please have a look at the SSCCE. How can I make the non-selected tree nodes' background transparent. At the moment the background of non-selected nodes is white. My cell renderer, however, should paint it non-opaque if it is not selected (and green when selected...what it does). In the end I want non-selected nodes to be just text without background, since the area which is red in the SSCCE has a gradient fill in my application. import java.awt.BorderLayout; import java.awt.Color; import java.awt.Component; import java.awt.Container; import javax.swing.JFrame; import javax.swing.JScrollPane;

The goal to write the values of columns into JTable vertically. I read about DefaultTableCellRenderer , VerticalTableHeaderCellRenderer() but cannot implement it. Here is my code: //========================================================= private JScrollPane getTablePane() { if (tablePane == null) { tablePane = new JScrollPane(); tablePane.setRowHeaderView(getTableDictionary()); tablePane.setViewportView(getTableDictionary()); } return tablePane; } //============================================================= private JTable getTableDictionary(){ if (table == null) { rowVector = new String
