您好強大的編程人員,再次作爲初學者的n00b我要求你的幫助......最終組合和SelectionListener中
問題如下,我有一個子窗口,包含一些標籤,按鈕和兩個下拉菜單。我想在一個名爲'name'的組合框上有一個SelectionListener,這樣從這個下拉列表中選擇的值將影響第二個組合框中的選定值。
如何做到這一點?
如果我取消
在name.addSelectionListener(new SelectionAdapter())
//desc.select(name.getSelectionIndex());
日食要我改變組合遞減和組合名決賽,這是不可能的因爲真的需要初始化它們在循環外毀了我佈局:(
這裏是代碼:
public void tariffAddWindow(final Shell childWindow) {
childWindow.setText("add dialog");
labels = new Label[operatorTariffData.getColumnNames().length];
inputTexts = new Text[operatorTariffData.getColumnNames().length];
final Button buttons[] = new Button[operatorTariffData.getColumnNames().length];
Combo name = null;
Combo desc = null;
for (int i =1; i< operatorTariffData.getColumnNames().length; i++) {
labels[i] = new Label(childWindow, SWT.NONE);
labels[i].setText(operatorTariffData.getColumnNames()[i].toString());
labels[i].setBackground(blue);
if (i == 3) {
name = new Combo(childWindow, SWT.READ_ONLY | SWT.BORDER);
name.setLayoutData(tLayout);
buttons[i] = new Button(childWindow, SWT.PUSH);
buttons[i].setText("e");
} else if (i == 4) {
desc = new Combo(childWindow, SWT.READ_ONLY | SWT.BORDER);
desc.setLayoutData(tLayout);
buttons[i] = new Button(childWindow, SWT.PUSH);
buttons[i].setText("e");
} else {
inputTexts[i] = new Text(childWindow, SWT.None);
//texts[i].setText(data.getData()[i].toString());
inputTexts[i].setLayoutData(tLayout);
buttons[i] = new Button(childWindow, SWT.TOGGLE);
buttons[i].setText("x");
buttons[i].setSelection(false);
}
}
for (int i = 1; i < contentProvider.getTariffNames().getQueryRowCount(); i++) {
name.add(contentProvider.getTariffNames().getQueryData()[i][3].toString());
desc.add(contentProvider.getTariffNames().getQueryData()[i][2].toString());
}
name.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(SelectionEvent e) {
//desc.select(name.getSelectionIndex());
}
});
}
非常感謝你多:) – mentis
