我想'无限'旋转Codename One Toolbar中的命令(刷新命令)(直到加载完成,然后我想停止旋转,但图像仍然必须是可见的)。我可以更改图标以便开始旋转吗?我怎样才能达到这个结果?
旋转图标在旋转时不应该是可点击的,但这不应该难以实现。

您可以使用工具栏API和一点点黑客攻击。我创建了以下方法:
private Command myCommand = new Command("");
Form f = new Form("Test form");
Toolbar t = new Toolbar();
f.setToolbar(t);
Command back = new Command("Back") {
@Override
public void actionPerformed(ActionEvent evt) {
//Do stuff
}
};
back.putClientProperty("uiid", "BackCommand");
f.setBackCommand(back);
t.addCommandToLeftBar(back);
myCommand = new Command(YourProgressImage) {
@Override
public void actionPerformed(ActionEvent evt) {
//To show the progress when some actions are being performed
showTitleProgress(t);
//When you're done, discard the progress and restore your command
hideTitleProgress(t, myCommand);
}
}
myCommand.putClientProperty("TitleCommand", true);
t.addCommandToRightBar(myCommand);
f.show();
将它与工具栏API和您的表单一起使用,如下所示:
MyListWidget::MyListWidget(QWidget* parent)
: QListWidget(parent)
{
QItemSelectionModel* oldSelectionModel = selectionModel();
QItemSelectionModel* newSelectionModel = new QItemSelectionModel(model(), oldSelectionModel->parent());
setSelectionModel(newSelectionModel);
oldSelectionModel->deleteLater();
}
