I don't know if it still relevant, but I had the same problem and I found a
solution.
I have small popup (my Class extends DialogBox).
Inside the popup, I have a VerticalPanel. Inside this panel is a ScrollPanel
and a HorizontalPanel for some buttons. Inside the ScrollPanel is a
FlexTable.
Now, the user can add and remove rows in the FlexTable. I want to grow the
Dialog a bit, but when it gets too large, I want the ScrollPanel to have a
fixed height so that the scrollbars appear.
When the user removes elements from the table and gets beyond the critical
height, I want the dialog to shrink.
It's quite easy. Here is how I achieved it.
private void handlePanelHeight() {
String height = null;
if (table.getOffsetHeight() > MAX_PANEL_HEIGHT) {
height = String.valueOf(MAX_PANEL_HEIGHT);
} else {
height = String.valueOf(table.getOffsetHeight());
}
DOM.setStyleAttribute(scrollPanel.getElement(), "height", height);
}
In my example, I set MAX_PANEL_HEIGHT to 250.
I call this method when
- the dialog is opened
- the user adds a row
- the user removes a row
I hope this helps.
Best regards
Denny
