Hello. I have two components, A and B, with hundreds of juce widgets. When A or B gains/losts the keyboard focus it gets repainted.
If A is focused, and one of his children components gains the focus A::focusLost() is called (and I’d paint it using Component::hasKeyboardFocus(true)), but then if I swich to B, A::focusLost() won’t be called (just A::childComp::focusLost()) , and A won’t be repainted.
Is it possible to call A::focusLost() when none of A’s children neither A have the focus?
the focus behaviour there looks correct. However, if you need to repaint A when a child loses the focus, can you have the child component signal repaint to the parent.
ie override Component::focusGained and focusLost and make them do that you want.
That means I might redefine all juce widgets overriding their focusGained() and focusLost(), and add a pointer to the parent (or grand-parent) I want to repaint. Too messy.
Must be something simpler and less alike spaghetti code, isn’t it?
See the FocusChangeListener class?
Yes, that did the trick, however I was expecting something like to a function in Component that could deal with that.
Anyway I post the code here, maybe someone can need it:
[code]class A: public Component,
public FocusChangeListener
{
public:
A();
~A();
virtual void globalFocusChanged(Component* focusedComponent);
private:
bool m_bIHaveTheFocus;
JUCE_LEAK_DETECTOR(A)
};[/code]
[code]A::A():
m_bIHaveTheFocus(false)
{
Desktop::getInstance().addFocusChangeListener(this);
}
A::~A()
{
Desktop::getInstance().removeFocusChangeListener(this);
}
void A::globalFocusChanged(Component* focusedComponent)
{
Component* comp = focusedComponent;
bool IhaveFocus = false;
while (comp != 0)
{
if (comp == this)
{
IhaveFocus = true;
comp = 0;
}
else
{
comp = comp->getParentComponent();
}
}
if (IhaveFocus != m_bIHaveTheFocus)
{
m_bIHaveTheFocus = IhaveFocus;
repaint();
}
}
[/code]
