My code looks like this.
SubscribeToEvent(E_ITEMSELECTED, URHO3D_HANDLER(HelloGUI, HandleControlSelected));
void HelloGUI::HandleControlSelected(StringHash eventType, VariantMap &eventData)
{
auto *el = static_cast<DropDownList *>(eventData[UIMouseClick::P_ELEMENT].GetPtr());
if (el) {
TypeInfo info = *el->GetTypeInfo();
String type = info.GetTypeName();
Log::Write(LOG_INFO, type);
}
}
Where do I go from here?
I did solve it. For anyone else looking for the same answer. Here’s my solution to watch UI elements and how to fetch their info.
First setup some event listeners
SubscribeToEvent(E_UIMOUSECLICK, URHO3D_HANDLER(HelloGUI, eventManager));
SubscribeToEvent(E_SLIDERCHANGED, URHO3D_HANDLER(HelloGUI, eventManager));
SubscribeToEvent(E_ITEMSELECTED, URHO3D_HANDLER(HelloGUI, eventManager));
SubscribeToEvent(E_FOCUSED, URHO3D_HANDLER(HelloGUI, eventManager));
SubscribeToEvent(E_DEFOCUSED, URHO3D_HANDLER(HelloGUI, eventManager));
Then add the eventManager
void HelloGUI::eventManager(StringHash eventType, VariantMap &eventData)
{
auto *el = static_cast<UIElement *>(eventData[UIMouseClick::P_ELEMENT].GetPtr());
if (el) {
String name = el->GetName();
String evName = "";
String value = "";
TypeInfo info = *el->GetTypeInfo();
String type = info.GetTypeName();
bool fireEvent = false;
if(E_FOCUSED == eventType) {
evName = "FOCUS";
} else if(E_DEFOCUSED == eventType) {
evName = "BLUR";
} else if(E_UIMOUSECLICK == eventType) {
evName = "CLICK";
} else if(E_SLIDERCHANGED == eventType) {
evName = "SLIDE";
} else if(E_ITEMSELECTED == eventType) {
evName = "ITEMSELECTED";
}
if(type == "LineEdit" && (evName == "BLUR" || evName == "FOCUS")) {
LineEdit *lineEl = static_cast<LineEdit *>(el);
value = lineEl->GetText();
fireEvent = true;
} else if(type == "Slider" && evName == "SLIDE") {
using namespace SliderChanged;
float valueFloat = eventData[P_VALUE].GetFloat();
value = String(valueFloat);
fireEvent = true;
} else if(type == "Button" && evName == "CLICK") {
fireEvent = true;
} else if(type == "DropDownList" && evName == "ITEMSELECTED") {
DropDownList *ddEl = static_cast<DropDownList *>(el);
unsigned ddIndex = ddEl->GetSelection();
value = String(ddIndex);
fireEvent = true;
} else if(type == "CheckBox" && evName == "CLICK") {
auto* box = static_cast<CheckBox*>(eventData[Toggled::P_ELEMENT].GetPtr());
bool checked = box->IsChecked();
value = String(checked);
fireEvent = true;
}
if(fireEvent) {
Log::Write(LOG_INFO, evName + ": " + name + " " + type + " " + value);
}
}
}
