Hi
I think we had the same problem, and solved it with subclassing the
ULCTableTree and on client side the UITableTree.
At the client side, we fireActionPerformedULC when the leftMouseButton is
released.
The client class look like this:
public class UISingleClickTableTree extends UITableTree {
@Override
protected void postInitializeState() {
super.postInitializeState();
JTableTree tableTree = getBasicTableTree();
tableTree.addMouseListener(new SingleClickHandler());
}
private class SingleClickHandler extends MouseAdapter {
public void mouseReleased(MouseEvent event) {
super.mouseReleased(event);
if (event.getClickCount() == 1 &&
SwingUtilities.isLeftMouseButton(event)) {
singleClick(event);
}
}
}
private void singleClick(MouseEvent event) {
if (!isLocationInExpandControl(event.getX())) {
fireActionPerformedULC(null, event.getModifiers());
}
}
/**
* Checks, if mouseX is in the expandControllAreal (with +- icons).
In this case, do nothing, because swing already expanded or collapsed.
*
*/
private boolean isLocationInExpandControl(int mouseX) {
BasicTableTree tree = getBasicTableTree();
TreePath path = tree.getSelectedPath();
if (path == null) {
return false;
}
if (tree.getModel().isLeaf(path.getLastPathComponent())) {
return false;
}
BasicTreeUI ui = (BasicTreeUI) tree.getBasicTree().getUI();
int boxWidth = 8;
if (ui.getExpandedIcon() != null) {
boxWidth = ui.getExpandedIcon().getIconWidth();
}
int totalIndent = ui.getLeftChildIndent() +
ui.getRightChildIndent();
int boxLeftX = (totalIndent * (path.getPathCount() - 1)) -
ui.getRightChildIndent() - boxWidth / 2;
boxLeftX = boxLeftX + tree.getInsets().left;
int boxRightX = boxLeftX + boxWidth;
return mouseX >= boxLeftX && mouseX <= boxRightX;
}
}
Hope to help
Stefan

Hi Christian,
In the tree, on a left click we want to open a page and on the right
click, we have the context menu. However, since a single click (either
left or right) triggers the selection event, the page opens even on a
right click. We want to avoid this.
Thanks & Regards,
Pavan

Subject: Re: [ULC-developer] Events for ULCTree
Hi Pavan,
in ULC one click triggers the selection and two clicks an action
event. The selection is the consequence of a mouse click
but should not have any connection to it. This is the same in Swing.
Usually the right click is reserved for activating the context menu.
What do you want to achieve with a right click on the tree? Best,
christian
