Customize the window in windows ?

[iNewLegend]

Hello im good C++ developer , but i never used qt im total new in it, i wonder how to make the next setps by using codes not UI , in my image i selected the things i want done in red color , i used

w.setWindowFlags(Qt::FramelessWindowHint);

w.setWindowFlags(Qt::FramelessWindowHint);

To copy to clipboard, switch view to plain text mode 

to hide windows one

cloud someone post me a code witch i can use QPushButton to make Close, and Mimimize buttons?



thanks in advance


-----------------------------------------------------------

my next code :

int main(int argc, char *argv[])
{
    QApplication    App(argc, argv);
    QWidget         MainWnd;
    QVBoxLayout     Layout;
    QPushButton     CloseBt;
    QPushButton     MimimizeBt;
    // ----
    CloseBt.setText("X");
    // ----
    MimimizeBt.setText("_");
    // ----
    Layout.addWidget(& CloseBt, 0, Qt::AlignRight | Qt::AlignTop);
    Layout.addWidget(& MimimizeBt, 2, Qt::AlignRight | Qt::AlignTop);
    // ----
    MainWnd.setLayout(& Layout);
    MainWnd.setWindowFlags(Qt::FramelessWindowHint);
    MainWnd.resize(800, 600);
    MainWnd.show();
    // ----
    return App.exec();
}

int main(int argc, char *argv[])
{
    QApplication    App(argc, argv);
    QWidget         MainWnd;
    QVBoxLayout     Layout;
    QPushButton     CloseBt;
    QPushButton     MimimizeBt;
    // ----
    CloseBt.setText("X");
    // ----
    MimimizeBt.setText("_");
    // ----
    Layout.addWidget(& CloseBt, 0, Qt::AlignRight | Qt::AlignTop);
    Layout.addWidget(& MimimizeBt, 2, Qt::AlignRight | Qt::AlignTop);
    // ----
    MainWnd.setLayout(& Layout);
    MainWnd.setWindowFlags(Qt::FramelessWindowHint);
    MainWnd.resize(800, 600);
    MainWnd.show();
    // ----
    return App.exec();
}

does it:

To reply strict to your question you can add this in your code:

QObject::connect(&MimimizeBt, SIGNAL(clicked()), &MainWnd, SLOT(showMinimized()));
    QObject::connect(&CloseBt, SIGNAL(clicked()), &MainWnd, SLOT(close()));

QObject::connect(&MimimizeBt, SIGNAL(clicked()), &MainWnd, SLOT(showMinimized()));
    QObject::connect(&CloseBt, SIGNAL(clicked()), &MainWnd, SLOT(close()));

To copy to clipboard, switch view to plain text mode 

And now a suggestion: use the heap for the child widgets (widgets that have a parent or will be "parented" by other widgets) - basically everything else then MainWnd.
***//else you can have some double-delete crash when close the application.

LE: you can read more about signals and slots here

***And a correction - on a second thought: the double-delete is not the cause of the crash - but the order of the delete the meta-object will call delete for a stack allocated object causing an error (only if the parent is deleted before the child)

thanks bro , but main problem is the gui , i mean i dont know how to make it align normaly with size and be like this order , first mimmize box , then close box , extaly what i showed in the first image

[Zlatomir]

Use a QHBoxLayout instead QVBoxLayout and add Minimize button first then Close.

thanks bro but they dont near ...

the close in center and mimimize in left

[Zlatomir]

I don't understand your problem, do you want the buttons to be smaller?

Or the order is not right?
Have you reversed this lines, like:

QHBoxLayout Layout;
    //...
    Layout.addWidget(& MimimizeBt, 2, Qt::AlignRight | Qt::AlignTop);
    Layout.addWidget(& CloseBt, 0, Qt::AlignRight | Qt::AlignTop);

QHBoxLayout Layout;
    //...
    Layout.addWidget(& MimimizeBt, 2, Qt::AlignRight | Qt::AlignTop);
    Layout.addWidget(& CloseBt, 0, Qt::AlignRight | Qt::AlignTop);

To copy to clipboard, switch view to plain text mode 

Or you can attach another print-screen so that we will see what is going on.

never mind my code now looks like this

#include <QtGui>
 
//--------------------------------------------------------------------------------------------------------------------------------------------
 
int main(int argc, char *argv[])
{
    QApplication    App(argc, argv);
    QWidget         MainWnd;
    QHBoxLayout     Layout;
    QPushButton     CloseBt;
    QPushButton     MimimizeBt;
    // ----
    CloseBt.setText("X");
    // ----
    MimimizeBt.setText("_");
    // ----
    Layout.setSpacing(1);
    Layout.setAlignment(Qt::AlignTop | Qt::AlignRight);
    Layout.addWidget(& MimimizeBt);
    Layout.addWidget(& CloseBt);
    // ----
    QObject::connect(& MimimizeBt, SIGNAL(clicked()), &MainWnd, SLOT(showMinimized()));
    QObject::connect(& CloseBt, SIGNAL(clicked()), &MainWnd, SLOT(close()));
 
    MainWnd.setLayout(& Layout);
    MainWnd.setWindowFlags(Qt::FramelessWindowHint);
    MainWnd.resize(800, 600);
    MainWnd.show();
    // ----
    return App.exec();
}
//--------------------------------------------------------------------------------------------------------------------------------------------

int main(int argc, char *argv[])
{
    QApplication    App(argc, argv);
    QWidget         MainWnd;
    QHBoxLayout     Layout;
    QPushButton     CloseBt;
    QPushButton     MimimizeBt;
    // ----
    CloseBt.setText("X");
    // ----
    MimimizeBt.setText("_");
    // ----
    Layout.setSpacing(1);
    Layout.setAlignment(Qt::AlignTop | Qt::AlignRight);
    Layout.addWidget(& MimimizeBt);
    Layout.addWidget(& CloseBt);
    // ----
    QObject::connect(& MimimizeBt, SIGNAL(clicked()), &MainWnd, SLOT(showMinimized()));
    QObject::connect(& CloseBt, SIGNAL(clicked()), &MainWnd, SLOT(close()));

    MainWnd.setLayout(& Layout);
    MainWnd.setWindowFlags(Qt::FramelessWindowHint);
    MainWnd.resize(800, 600);
    MainWnd.show();

and its looks like this:


how can i change size of buttons? so they will be more smaller
thanks again

[Zlatomir]

You can use setMaximumWidth(...)
