I am learning Dlang and Dlangui.

I encounter, a little problem on:

  how to center dlangui window on screen.

How to set the window width and height outside the constructor

How to maximize and minimize the window using code.

How to set global font for the application.  The font display is 
not too nice.

I have check online, the documentation  and available tutorial to 
no help

Thanks in advance

For a little bit of information look at: 
https://github.com/buggins/dlangui/pull/372

Without going into depth I have tested this under Linux/GTK with 
dlangui:

     WindowState state;
     Rect    rect;
     rect.left   = 800;
     rect.top    = 10;
     rect.bottom = 600;
     rect.right  = 1000;
     bool bRet= window.setWindowState(state,
                                      false,
                                      rect);

     window.show();

This changed the position and size of my initial window.

This help a little but not what I am looking for.
I want to calculate the width and window of the screen so as to 
center my window on screen

I also notice that a window of 350 x 550 appear bigger compare to 
the same Widow dimension in Havana and adobe air.

Why is it so?

Plz help!  Thanks in advance

To center horizontal:

l = left
s = screen width
w = window width

l = (s / 2) - (w / 2)

To center vertical:

t = top
s = screen height
h = window height

t = (s / 2) - (h / 2)

And about the window size.

It has probably to do with the type of Window you're rendering, 
like whether it has borders or not. Borders are not calculated in 
the width / height, so they take up extra space. Adobe usually 
never uses the native GUI for borders etc. so the border size (if 
there is one) is included in their width / height.

Which class in dlangui is use to obtain the screen height and 
width?
A Windom of dimension 280 x 445 in dlangui is the same as a 
Windom of 350 x 550 in Javafx and adobe air.

What could be responsible for this wide difference?
A window of 350 x 550 in adobe air is the same as a window of 350 
x 550 in javafx. So why is dlangui window bigger?

Note that I  am using  w x h for my window dimension and I am on 
windows 10

That looks like DPI scaling is in effect: 280 pixels + 125% DPI = 
350.

There's an example of how to get the screen size here (look for 
getScreenDimensions):
