Current title

We can use onHeaderClick, onHeaderRightClick or onHeaderDoubleClick to get current header that user clicked, in here, we use onHeaderDoubleClick as a example.

1. we can get clicked header type by

HeaderMouseEvent.getType();

2. we can get header title by

public void onHeaderDoubleClick$spreadsheet(HeaderMouseEvent event) {
	String currentTitle = null;
	int headerType = event.getType();
	if (headerType == HeaderEvent.TOP_HEADER) {
		currentTitle = spreadsheet.getColumntitle(currentIndex);
	} else {
		currentTitle =  spreadsheet.getRowtitle(currentIndex);
	}
...

3. Then, set the current header title to textbox and open the popup.

Popup inputTitlePopup;
Textbox titleEditor;

public void onHeaderDoubleClick$spreadsheet(HeaderMouseEvent event) {
...
	inputTitlePopup.open(event.getPageX(), event.getPageY());
	titleEditor.setText(currentTitle);
	titleEditor.focus();
}

Edit title

We can change column title when use click Enter

public void onOK$titleEditor() {
	HashMap<Integer, String> titles = new HashMap<Integer, String>();
	titles.put(Integer.valueOf(currentIndex), titleEditor.getText());
	
	if (isColumnHeader) {
		spreadsheet.setColumntitles(titles);
	} else {
		spreadsheet.setRowtitles(titles);
	}
	inputTitlePopup.close();
}

Click Enter to change title

Cancel editing

Close popup when user click Esc

public void onCancel$titleEditor() {
	inputTitlePopup.close();
}
