How to emulate mouse click using wxWidgets - wxwidgets

Question

Is there any function in wxWidgets framework, say, click(), whose function is to emulate a left-click mouse?

Answer 1

No, there is no function like this. If you really need to do it, e.g. because you want to perform some action in another application you need to write platform-specific code yourself (e.g. use SendInput() under Windows).
If you want to use this to execute some code in your own application though, there is a much better solution: instead of doing unsupported, fragile and ugly
void MyClass::OnLeftUp(wxMouseEvent& event)
{
... do something with click at event.GetPosition() ...
}
void MyOtherFunction()
{
wxMouseEvent event(...);
... initialization not shown because there is no right way to do it anyhow ...
myObject->ProcessEvent(event);
}
just refactor your code to do it like this instead:
void MyClass::OnLeftUp(wxMouseEvent& event)
{
HandleClick(event.GetPosition());
}
void MyClass::HandleClick(const wxPoint& pos)
{
... do something with click at pos ...
}
void MyOtherFunction()
{
myObject->HandleClick(position);
}

If you're just talking about emulating a click on another button in your wxWidgets app, I've tried this before:
Create a fake wxEvent of the right type, tell the event what object to care
about using SetEventObject(), and tell a parent wxWindow in the hierarchy to
ProcessEvent(myNewEvent). You might want to use wxGetTopLevelParent() to get the topmost frame/dialog
If you are talking about emulating a click in another, non-wxWidgets process, it's possible you could use the OS's accessibility APIs to do this. wxAccessibility should be able to help with this on Windows -- for other OSes, last I heard (granted, a few years ago), you'll have to use the native OS functions.

You can use the wxControl::Command() method. According to Documentation:
Simulates the effect of the user issuing a command to the item.
Documentation page
List of events to use with wxCommandEvent constructor
You can simulate a click on a button like this:
$this->MyButton->Command(new wxCommandEvent(wxEVT_COMMAND_BUTTON_CLICKED));
There is also the wxUIActionSimulator class that you can use to simulate UI actions.
