Purpose

ZK Spreadsheet uses Range.getEditText() to get cell's edit text, and Range.setEditText(String)to set cell's text as input by the user.

ZUML

<zk>
<div width="100%" height="100%" apply="demo.EditorComposer" >
	<div height="3px"></div>
		<combobox id="focusCombobox" mold="rounded"	style="text-align:center;">
		</combobox>
		<textbox id="formulaEditor" cols="100"/>
	<div height="3px"></div>
	<spreadsheet id="spreadsheet" src="/demo_sample.xls"	
			maxrows="200" 
			maxcolumns="40"
			width="100%"
			height="450px"></spreadsheet>
</div>
</zk>

Current Cell Text

We can use onCellFocused event to get the current focus cell and display the cell's text.

public void onCellFocused$spreadsheet(CellEvent event) {
	int row = event.getRow();
	int col = event.getColumn();
	focusCombobox.setText(spreadsheet.getRowtitle(row) + spreadsheet.getColumntitle(col));

	Worksheet sheet = spreadsheet.getSelectedSheet();
	currentCell = Utils.getCell(sheet, row, col);
	currentRange = Ranges.range(sheet, row, col);
	formulaEditor.setText(currentRange.getEditText());
}

Cell Position

First, we need to get the current cell's position. We can get row and column index from CellEvent, then use Spreadsheet.getRowtitle(String) and Spreadsheet.getColumntitle((String) to get the current cell's title.

public void onCellFocused$spreadsheet(CellEvent event) {
	int row = event.getRow();
	int col = event.getColumn();
	focusCombobox.setText(spreadsheet.getRowtitle(row) + spreadsheet.getColumntitle(col));
 ...

Cell Value

After we get the cell's position, we can get the cell's value from Range.getEditText()

public void onCellFocused$spreadsheet(CellEvent event) {
        ...

	Worksheet sheet = spreadsheet.getSelectedSheet();
	currentCell = Utils.getCell(sheet, row, col);
	currentRange = Ranges.range(sheet, row, col);
	formulaEditor.setText(currentRange.getEditText());
}

Editor

For editor, we can use the onOK event, which menus when the user click Enter keyboard, set cell's value and make spreadsheet's focus to the next cell

public void onOK$formulaEditor() {
	currentRange.setEditText(formulaEditor.getText());
	spreadsheet.focusTo(currentCell.getRowIndex() + 1, currentCell.getColumnIndex());
}

Second, we can also use the onChange and onChanging event to get the current editor's value and set the cell's value.

public void onChanging$formulaEditor(InputEvent event) {
	if (currentCell.getCellType() != Cell.CELL_TYPE_FORMULA)
		currentRange.setEditText(event.getValue());
}
	
public void onChange$formulaEditor() {
	currentRange.setEditText(formulaEditor.getText());
}
