How to access UI from another function?

[MasterBlade]

Hello I'm new to Qt. I created a project that called another function in mainwindow. It looks like this

void Gameplay::on_startgame_clicked()
{
Game_Initialize();

}

However when I tried to access ui in the new function like the following. It said that ui is not registered. What should I do? Many thanks!

void Game_Initialize(){
ui->deg->setText("D: ");
}

Hi and welcome to devnet,

Your Game_Initialized method is just a free function. Make it a member of your Gameplay class. Or since the method only updates the content of your UI, write that code directly in on_startgame_clicked.

@MasterBlade From the code you showed, the Game_Initialize() function does not look like it is part of the Gameplay class which means it has no idea what ui is.

So that's either a typo and you meant to do void Gameplay::Game_Initialize() or it's outside the class intentionally, in which case you will need to pass the ui pointer to it. However be aware that would be a really bad way to use Qt. Hopefully it's the former and you meant it to be in the class.
