ZK Spreadsheet use Range.getEditText() to get cell's edit tet, and Range.setEditText(text) to set cell's text as input by user.
Scenario
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>
Current Cell
We can use onCellFocused event to get current focus cell.
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());
}
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());
}
