QOpenGLWidget not drawing anything
I have gone through many tutorials for just simply rendering a triangle using a promoted widget in Qt and it doesn't matter what code I use but my triangle refuses to show, I have seen a QOpenGLWindow be used and it worked fine but I am trying to work on a map editor, so in short I need help figuring out why my code refuses to work whether I use GLEW functions or Qt's OpenGL implementations, here's my code.
p.s. The way everything is formatted is just so I can get it working, I have been at this for two days and have just finally given up on trying different things, also the AhtuViewport constructor is called when the mainwindow is shown and glClearColor works but nothing draws.
Main:
#include "AhtuApp.h"
int main(int argc, char *argv)
{
AhtuApp app(argc, argv);
app.InitApp();
return app.exec();
}
App:
#include "AhtuApp.h"
AhtuApp::AhtuApp(int &argc, char **argv)
: QApplication(argc, argv)
{}
void AhtuApp::InitApp()
{
ahtuWin = new AhtuWindow();
ahtuWin->show();
}
Window:
#include "AhtuApp.h"
#include "ui_AhtuWindow.h"
AhtuWindow::AhtuWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::AhtuWindow)
{
ui->setupUi(this);
}
AhtuWindow::~AhtuWindow()
{
delete ui;
}
