Grid - double click on column header [message #58019]

Hello,

In my application a double click on a grid column header should open a
dialog. If I do this

grid.addMouseListener(new MouseAdapter() {
public void mouseDoubleClick(MouseEvent e) {
if (e.y < grid.getHeaderHeight()) {
// open dialog
}
}
});

then the dialog gets open also when I double click the column header
divider to auto size the column, which should not happen.

My current work around was to:

1) change the grid source file to have access to hoveringOnColumnResizer
private member, so in my client code I could do

grid.addMouseListener(new MouseAdapter() {
public void mouseDoubleClick(MouseEvent e) {
if (e.y < grid.getHeaderHeight()
&& !grid.hoveringOnColumnResizer)
{
// open dialog
}
}
});

2) change the beginning of grid.onMouseDoubleClick(MouseEvent e) method
like this

if (hoveringOnColumnResizer)
{
int dw = columnBeingResized.getWidth(); // added
columnBeingResized.pack();
dw -= columnBeingResized.getWidth(); // added
resizingColumn = false;
handleHoverOnColumnResizer(e.x-dw, e.y); // modified
return;
}

My question: is there a simpler way to achieve this and if not could we
have it implemented in the mainstream version?

Cheers
Jacek

Hi,

No not yet :-(. In my current fork I have also had this problem in my
current project where I forked the grid and what I did was to adjust the
grids mouse handlers to use the addListener()-API and customize the
detail field of the event object (holding all the booleans used internally).

Could you please file a bug report and we can discuss there how we can
achieve better event support?
