Get or Set Value, Formula, or Formatted Text

ZK Spreadsheet can use Range.setEditText(text) to set cell's text as input by user.

Purpose

Implement a formula editor to allow user input text, formula etc. For this function, we can use a Combobox to show the current cell, and use Textbox as a editor

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

onCellFocused

Cell position

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

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

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