Cell selection in TableView
Hi, all. I want to realize a cell selection in table View. I try to rewrite
TerraTableViewSkin, but some my cells is never highlighted and I can't
understand why... I add a few line of code in TerraTableViewSkin in paint
method:
..................................................................
// Paint the cells
columnX = 0;
for (int columnIndex = 0, columnCount = columns.getLength();
columnIndex < columnCount; columnIndex++) {
boolean cellHighlighted = (columnIndex==highlightColumnIndex);
Color cellBackgroundColor = null;
if (cellHighlighted && rowHighlighted){
System.out.println("cellBackgroundColor");
cellBackgroundColor = (tableView.isFocused())
? this.selectionCellBackgroundColor :
inactiveCellSelectionBackgroundColor;
}
int columnWidth = columnWidths.get(columnIndex);
if (cellBackgroundColor!=null){
graphics.setPaint(cellBackgroundColor);
graphics.fillRect(columnX, rowY, columnWidth,
rowHeight);
}
TableView.Column column = columns.get(columnIndex);
..........................................................................................
and in mouseMove method:
@Override
public boolean mouseMove(Component component, int x, int y) {
boolean consumed = super.mouseMove(component, x, y);
TableView tableView = (TableView)getComponent();
int previousHighlightRowIndex = this.highlightRowIndex;
highlightRowIndex = getRowAt(y);
int previousHighlightColumnIndex = this.highlightColumnIndex;
highlightColumnIndex = getColumnAt(x);
if (previousHighlightRowIndex != highlightRowIndex
&& tableView.getSelectMode() != TableView.SelectMode.NONE
&& showHighlight) {
if (previousHighlightRowIndex != -1) {
repaintComponent(getRowBounds(previousHighlightRowIndex));
}
if (highlightRowIndex != -1 ) {
repaintComponent(getRowBounds(highlightRowIndex));
}
}
if (highlightColumnIndex != previousHighlightColumnIndex
&& showHighlight){
repaintComponent(getRowBounds(previousHighlightColumnIndex));
System.out.println("column index - " + highlightColumnIndex);
if (highlightColumnIndex != -1) {
repaintComponent(getRowBounds(highlightColumnIndex));
}
}
return consumed;
}
But some of my cells is never highlighted on mouse move... My code to look
at and to test
http://perdunov.net/pivotcellteable.rar here
Please help me...
-----
Thank you!

Actually could not get it to work, maybe not compatible with current pivot...
Maybe there has been a change to the setText class, so it throws an error on
a null value...

I got to the bottom of this page feeling a bit depressed that this does not

That is up to your app, though I imagine it would be triggered by some user action such as clicking on a column header.

This is I understand. I mean where and how this property can be changed? In
my renderer I can do column.getSelected()... But If while creation it is
setted to "false" and don't change? I always get "false". And I ask where
property of Column "selected" is changed?

You'll need to create a custom subclass of TableView.Column and add a "selected" property to it.

Re: Cell selection in TableView

Unless you modify the skin, you won't be able to highlight an individual cell on mouse-over, but you can use the renderer to paint a "selected" state for a column. One way to do this would be to create a subclass of TableView.Column and add a boolean "selected" property. Then your renderer can get a reference to the column and set an appropriate background color when "selected" = true.
Though you can't easily highlight the cell as the mouse moves over it, you can highlight the cell when the user clicks on it, since this will invoke the editor.

Ok, I look at TableViewCellRenderer.... I should extend this renderer to

public void render(Object row, int rowIndex, int columnIndex,
TableView tableView, String columnName,

Can you give me please a short example that I can understand an idea?

You probably can, but writing a skin is a lot more involved than writing a renderer.

OK. I think you could probably do this by writing a cell editor that doesn't actually edit its contents. See the TableView row editor demo for an example.

It needs just select a cell, and highlight row and column which contains this
cell(like on the picture). When row is selected I need to know its position
in the table (rowIndex and columnIndex). When I select it I want to navigate
with keypad to adjacent cells (just highlight them). And when mouse is over
the cell it must just highlight the cell. And I want to continue select a
row too, to obtain the data from this row.

Re: Cell selection in TableView

I guess it depends on what you need to do. TableView's selection model is row-based, not cell-based. What does your app need to do when you select a cell?

TableView isn't really designed to support single-cell selection, though it is possible to implement a single-cell editor.
