Get or Set Value, Formula, or Formatted Text



Purpose

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

Composer

Current cell text

We can use onCellFocused event to get current focus cell and display 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));

	Sheet 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, column index from CellEvent, then use Spreadsheet.getRowtitle(String) and Spreadsheet.getColumntitle((String) 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());
}

Editor

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

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

Second, we can also use onChange and onChanging event to get current editor's value and set 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());
}
