一提到表格，人們就想得到EXCEL。不錯(cuò)，這個(gè)優(yōu)秀的軟件一共提供了幾千個(gè)功能點(diǎn)，但人們平常一般只用到其常用的幾十個(gè)功能。
SWT/JFACE提供的表格雖然不能完成EXCEL的所有功能，但其常用的功能已經(jīng)具備。比如：雙擊編輯表格、操作單元格、在單元格中加入控件。
其關(guān)鍵就在于CellEditor的使用！
for (int i=0; i<items.length; i++) 
{
TableEditor editor = new TableEditor (table);
CCombo combo = new CCombo (table, SWT.NONE);
combo.setText("CCombo");
combo.add("item 1");
combo.add("item 2");
editor.grabHorizontal = true;
editor.setEditor(combo, items[i], 0);
editor = new TableEditor (table);
Text text = new Text (table, SWT.NONE);
text.setText("Text");
editor.grabHorizontal = true;
editor.setEditor(text, items[i], 1);
editor = new TableEditor (table);
Button button = new Button (table, SWT.CHECK);
button.pack ();
editor.minimumWidth = button.getSize ().x;
editor.horizontalAlignment = SWT.LEFT;
editor.setEditor (button, items[i], 2);
}
用以上代碼加入CCombo和Check。
關(guān)鍵在于：
editor.setEditor(combo, items[i], 0);
combo為控件對(duì)象，item[i]和0為確定editor（單元格）的位置。
有了這個(gè)函數(shù)就可以任意加控件了。特殊情況加入text控件就可實(shí)現(xiàn)雙擊編輯，代碼如下：
table.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(SelectionEvent e) {
// Clean up any previous editor control
Control oldEditor = editor.getEditor();
if (oldEditor != null) oldEditor.dispose();
// Identify the selected row
TableItem item = (TableItem)e.item;
if (item == null) return;
// The control that will be the editor must be a child of the Table
Text newEditor = new Text(table, SWT.NONE);
newEditor.setText(item.getText(EDITABLECOLUMN));
newEditor.addModifyListener(new ModifyListener() {
public void modifyText(ModifyEvent me) {
Text text = (Text)editor.getEditor();
editor.getItem().setText(EDITABLECOLUMN, text.getText());
}
});
newEditor.selectAll();
newEditor.setFocus();
editor.setEditor(newEditor, item, EDITABLECOLUMN);
}
});
哈哈 這樣就可以了哦！
