Current Range
We can get the user's selection range from onCellSelection event.
Range currentRange;
public void onCellSelection$spreadsheet(CellSelectionEvent event) {
currentRange = Ranges.range(event.getSheet(), event.getTop(), event.getLeft(),
event.getBottom(), event.getRight());
}
Open Header Menu
We can open menu when the user right clicks on the header using onHeaderRightClick.
private Menupopup headerMenupopup;
public void onHeaderRightClick$spreadsheet(HeaderMouseEvent event) {
headerMenupopup.open(event.getPageX(), event.getPageY());
}
Hide Header
When the user clicks hide it will hide the header in the selected range.
private Menuitem hide;
public void onClick$hide() {
if (currentRange != null) {
currentRange.setHidden(true);
currentRange = null;
}
}
Show Header
When the user clicks show it will show the hidden header in the selected range.
private Menuitem show;
public void onClick$show() {
if (currentRange != null) {
currentRange.setHidden(false);
currentRange = null;
}
}
Select the range which includes hidden range
Show hidden range
