Checkable for QAction

Qt Enthusiast

QAction * action1 = act = new QAction(QIcon(":/images/my.png"), tr(" View"), this);
connect(act, SIGNAL(triggered()), d_view, SLOT(showView1()));
act->setCheckable(true);

QAction * action2 = act = new QAction(QIcon(":/images/my1.png"), tr(" View"), this);
connect(act, SIGNAL(triggered()), d_view, SLOT(showView2()));
act->setCheckable(true);

it is part of group of Actions

QActionGroup viewGroup = new QActionGroup(this);
d_viewGroup->addAction(action1);
d_viewGroup->addAction(action2);
action1->setChecked(true);

When I click on action1 for first time the slot showView1 gets called butwhen I again click on action1 the showView1 does not get called

What is reason for that . If I want to two actions to be mutually exclusive but the respective slots should be called on every click on the action . how to do that

Hi,

That's because triggered doesn't get fired when calling setChecked. You should use toggled

Qt Enthusiast

QAction * action1 = act = new QAction(QIcon(":/images/my.png"), tr(" View"), this);
connect(act, SIGNAL(toggled(bool)), d_view, SLOT(showView1(bool)));
act->setCheckable(true);

QAction * action2 = act = new QAction(QIcon(":/images/my1.png"), tr(" View"), this);
connect(act, SIGNAL(toggled()), d_view, SLOT(showView2(bool)));
act->setCheckable(true);

it is part of group of Actions

QActionGroup viewGroup = new QActionGroup(this);
d_viewGroup->addAction(action1);
d_viewGroup->addAction(action2);
action1->setChecked(true);

the toggled is called whenever there is change in state of QAction . In this case event if I connect to toggled(bool) then also

If I click on action1 , then showView2 slot is called two times one with true bool and other with false bool
if I click on action2 , then also showView1slot is called two times one with true bool and other with false bool

My requirement when I a call any action only that action should be called not other action in the group should be called and also when I click on the action any time the respective slot should be called like a menu item

Because by default QActionGroup is exclusive, call QActionGroup::setExclusive(false)

Qt Enthusiast

if I QActionGroup::setExclusive(false) and then have

QAction * action1 = act = new QAction(QIcon(":/images/my.png"), tr(" View"), this);
connect(act, SIGNAL(toggled(bool)), d_view, SLOT(showView1(bool)));
act->setCheckable(true);

QAction * action2 = act = new QAction(QIcon(":/images/my1.png"), tr(" View"), this);
connect(act, SIGNAL(toggled()), d_view, SLOT(showView2(bool)));
act->setCheckable(true);

it is part of group of Actions

QActionGroup viewGroup = new QActionGroup(this);
d_viewGroup->addAction(action1);
d_viewGroup->addAction(action2);
action1->setChecked(true);

Will it possible when I click I action1 the only action1 is will excuted and if I click on action2 then only action2 will be executed

SGaist

Isn't that what's happening when setting exclusive to false ?

Qt Enthusiast

As I understand if we I

QActionGroup::setExclusive(true) and then have

QAction * action1 = act = new QAction(QIcon(":/images/my.png"), tr(" View"), this);
connect(act, SIGNAL(triggered()), d_view, SLOT(showView1(bool)));
act->setCheckable(true);

QAction * action2 = act = new QAction(QIcon(":/images/my1.png"), tr(" View"), this);
connect(act, SIGNAL(triggered()), d_view, SLOT(showView2(bool)));
act->setCheckable(true);

it is part of group of Actions

QActionGroup viewGroup = new QActionGroup(this);
d_viewGroup->addAction(action1);
d_viewGroup->addAction(action2);
action1->setChecked(true);

----------------------it works like group of radiobuttons-------------------

but if we have a

I QActionGroup::setExclusive(false) and then have

QAction * action1 = act = new QAction(QIcon(":/images/my.png"), tr(" View"), this);
connect(act, SIGNAL(toggled(bool)), d_view, SLOT(showView1(bool)));
act->setCheckable(true);

QAction * action2 = act = new QAction(QIcon(":/images/my1.png"), tr(" View"), this);
connect(act, SIGNAL(toggled()), d_view, SLOT(showView2(bool)));
act->setCheckable(true);

it is part of group of Actions

QActionGroup viewGroup = new QActionGroup(this);
d_viewGroup->addAction(action1);
d_viewGroup->addAction(action2);
action1->setChecked(true);

then ------------------it is a drop down menu where each action will executed at once when click and when click it as another action the relevant slot will be called

Aren't you trying to reinvent the QRadioButton ?
