我有一个包含4列的表格,第四个填充有CHECK样式的按钮。
问题在于,每次我执行removeAll()来用其他内容填充表格时,按钮都不会被删除,因此我可以在同一行中看到具有相同状态的相同按钮。
这是我的桌子:
Table membersTable = new Table(clubComposite, SWT.BORDER | SWT.CHECK | SWT.FULL_SELECTION);
membersTable.setLinesVisible(true);
membersTable.setHeaderVisible(true);
membersTable.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true, 1, 1));
TableColumn tblclmnName = new TableColumn(membersTable, SWT.NONE);
tblclmnName.setWidth(150);
tblclmnName.setText("Nombre");
TableColumn tblclmnCommonPhoneNumber = new TableColumn(membersTable, SWT.NONE);
tblclmnCommonPhoneNumber.setWidth(120);
tblclmnCommonPhoneNumber.setText("Teléfono");
TableColumn tblclmnCommonMoney = new TableColumn(membersTable, SWT.NONE);
tblclmnCommonMoney.setWidth(150);
tblclmnCommonMoney.setText("Participación Habitual");
TableColumn tblclmnPayed = new TableColumn(membersTable, SWT.CENTER);
tblclmnPayed.setWidth(50);
tblclmnPayed.setText("Payed");
这是我填充表格的方式,您也可以看到按钮:
// populate Table
for (int i=0; i<50; i++) {
TableItem tableItem = new TableItem(membersTable, SWT.NONE);
tableItem.setText(new String[] {"person "+i, "610610620", "100"});
Button button = new Button(membersTable, SWT.CHECK);
button.pack();
TableEditor editor = new TableEditor(membersTable);
editor.minimumWidth = button.getSize().x;
editor.horizontalAlignment = SWT.CENTER;
editor.setEditor(button, tableItem, 3);
button.addSelectionListener(new SelectionAdapter() {
@Override
public void widgetSelected(SelectionEvent e) {
//how to know in which row is clicked the checkbox?
}
});
}
答案 0 :(得分:1)
TableEditor
不是TableItem
,不会被removeAll
删除(也不会被clearAll
删除)。
相应的控件可以通过编程方式放置,例如:
membersTable.removeAll();
Arrays.stream(membersTable.getChildren()) // stream over all children
.filter(Button.class::isInstance) // only the Buttons
.forEach(Control::dispose); // and dispose it
或(与上述相同)
membersTable.removeAll();
for(Control control : membersTable.getChildren()) {
if (control instanceof Button) {
control.dispose();
}
}
或者,将TableEditor
保存在列表中,并处置其编辑器:
List<TableEditor> editors = new ArrayList<>();
...
membersTable.removeAll();
editors.stream() // stream over TableEditors
.map(TableEditor::getEditor) // get their Editor (a Control)
.forEach(Control::dispose); // dispose it
editors.clear();
