示例1: deleteWidgetList
void FormWindowBase::deleteWidgetList(const QWidgetList &widget_list)
{
switch (widget_list.size()) {
case 0:
break;
case 1: {
commandHistory()->beginMacro(tr("Delete '%1'").arg(widget_list.front()->objectName()));
emit widgetRemoved(widget_list.front());
DeleteWidgetCommand *cmd = new DeleteWidgetCommand(this);
cmd->init(widget_list.front());
commandHistory()->push(cmd);
commandHistory()->endMacro();
}
break;
default:
commandHistory()->beginMacro(tr("Delete"));
foreach (QWidget *w, widget_list) {
emit widgetRemoved(w);
DeleteWidgetCommand *cmd = new DeleteWidgetCommand(this);
cmd->init(w);
commandHistory()->push(cmd);
}
commandHistory()->endMacro();
break;
}示例2: deleteWidgetList
void FormWindowBase::deleteWidgetList(const QWidgetList &widget_list)
{
// We need a macro here even for single widgets because the some components (for example,
// the signal slot editor are connected to widgetRemoved() and add their
// own commands (for example, to delete w's connections)
const QString description = widget_list.size() == 1 ?
tr("Delete '%1'").arg(widget_list.front()->objectName()) : tr("Delete");
commandHistory()->beginMacro(description);
foreach (QWidget *w, widget_list) {
emit widgetRemoved(w);
DeleteWidgetCommand *cmd = new DeleteWidgetCommand(this);
cmd->init(w);
commandHistory()->push(cmd);
}
