CEGUI sans mouse input Problem

Hey guys,
I am thinking about making a game with Ogre that uses the Xbox360 controller. I was wondering if there was a way that I could integrate the controllers d-pad (or the arrow buttons on the computer's keyboard) with CEGUI.
I only have like three menus so I was thinking that I could just have an array that contained each button. Then I would intially have the top button "hovered over", but I don't know if you can do this without a mouse. When the player hits the down arrow then the next button in the array would be "hovering".
Any ideas would be appreciated.

Hey guys,
I wrote some code to let me do what I want. I am putting it up so that someone else can use it if they need to or they can make it better.
Code: Select all
class ButtonContainerClass
{
public:
void addBtn(CEGUI::String); // Add a button to the container
void nextBtn(); // Move the selection to the next button
void prevBtn(); // Move the selection to the prev button
int getSize();
ButtonContainerClass(bool);
~ButtonContainerClass(void);
private:
void updateSelection();
std::vector<CEGUI::String> buttons; // Buttons are id'ed by name string
int cur_btn; // Index of current button
bool loop; // True if selection should go to beginning after the end
};
and here is the cpp
Code: Select all
ButtonContainerClass::ButtonContainerClass(bool loop_selection)
{
loop = loop_selection;
cur_btn = 0;
}
ButtonContainerClass::~ButtonContainerClass()
{
}
void ButtonContainerClass::addBtn(CEGUI::String btn_str)
{
buttons.push_back(btn_str);
if(buttons.size() == 1)
{
updateSelection();
}
}
int ButtonContainerClass::getSize()
{
return buttons.size();
}
void ButtonContainerClass::nextBtn()
{
if(cur_btn == buttons.size() - 1) // end of list
{
if(loop)
{
cur_btn = 0;
updateSelection();
}
}
else
{
cur_btn++;
updateSelection();
}
return;
}
void ButtonContainerClass::prevBtn()
{
if(cur_btn == 0) // start of list
{
if(loop)
{
cur_btn = buttons.size() - 1;
updateSelection();
}
}
else
{
cur_btn--;
updateSelection();
}
return;
}
void ButtonContainerClass::updateSelection()
{
CEGUI::Point pos = getWindow(buttons[cur_btn])->getPosition(CEGUI::MetricsMode::Absolute);
CEGUI::System::getSingleton().injectMousePosition(pos.d_x, pos.d_y);
return;
}By the way in order to use this class, you have to add the button name strings with the add function. Then I have it so when you press the arrow keys it either calls nextBtn or prevBtn.
Let me know if this helps anyone.
