Event handler of another frame not getting called - wxWidgets - c++

Question

Good day to all,
I'm working on a C++ program using wxWidgets wherein a frame has a button named "Calibrate Button" which is used to calibrate HSV values using a trackbar. When the user selects this button, a live feed video, a control panel which contains the trackbar for adjusting HSV values, a threshold image which represents the changes in the calibration of the HSV values, and another frame which contains a button named "SAVE VALUES" appears. When the user clicks the Save Values button, it saves whatever the values that have been set in the trackbar into a textfile.
My problem is, whenever i click that button, it does not perform what it is intended to do, which is to save the HSV values in a txtfile.
Here is the main code which is responsible for creating the additional frame when the user selects the Calibrate Button.
void TemplateFrame::OncalibTrackerButtonClick(wxCommandEvent& event)
{
**some code for initializing the live video feed, the trackbars, etc.**
CalibrationWindow* calibWindow = new CalibrationWindow(this);
calibWindow->setHSVvalues(H_MIN,S_MIN,V_MIN,H_MAX,S_MAX,V_MAX);
calibrationModeTracker = true;
**the following code after this line would be a pseudocode of what I am doing once the button has been click already
while(calibrationModeTracker){
calibWindow->Show(); // shows the "SAVE VALUES" frame
wxYield();
read live feed video
createTrackbars();
show live feed video
show threshold image
}
}
Inside the while loop, users would be able to click the "SAVE VALUES" button which would save the HSV values in a txtfile.
On the other hand, here is the event handler function of the newly created frame (CalibrationWindow.cpp) after clicking Calibrate Button which contains the Save Values button
void CalibrationWindow::OnSaveClick(wxCommandEvent& event)
{
ofstream myfile;
stringstream oss(stringstream::in | stringstream::out);
string f;
f = "//home//ianlangley//Desktop//Savefiles//HSVvalues_left.txt";
f = f.append(oss.str());
myfile.open(f.c_str());
if (myfile.is_open()){
myfile<<CalibrationWindow::getlow_H()<<"\n";
myfile<<CalibrationWindow::getlow_S()<<"\n";
myfile<<CalibrationWindow::getlow_V()<<"\n";
myfile<<CalibrationWindow::gethigh_H()<<"\n";
myfile<<CalibrationWindow::gethigh_S()<<"\n";
myfile<<CalibrationWindow::gethigh_V();
myfile.close();
}
}
Lastly, here is the code inside the header file: CalibrationWindow.h
class CalibrationWindow: public wxFrame
{
public:
CalibrationWindow(wxWindow* parent,wxWindowID id=wxID_ANY);
virtual ~CalibrationWindow();
void setHSVvalues(int lowH,int lowS, int lowV,int highH,int highS, int highV);
int getlow_H();
int getlow_S();
int getlow_V();
int gethigh_H();
int gethigh_S();
int gethigh_V();
//(*Declarations(CalibrationWindow)
wxButton* LeftHandButton;
wxButton* RightHandButton;
//*)
protected:
//(*Identifiers(CalibrationWindow)
static const long ID_BUTTON2;
static const long ID_BUTTON1;
//*)
private:
int lowH,lowS,lowV,highH,highS,highV;
//(*Handlers(CalibrationWindow)
void OnRightHandButtonClick(wxCommandEvent& event);
void OnLeftHandButtonClick(wxCommandEvent& event);
//*)
DECLARE_EVENT_TABLE()
};
Thank you to those who will be able to help me with this problem.
