如何将 MOTIF Widget 的主应用程序窗口居中在计算机屏幕的中心?例如这里的表单小部件。
代码已准备好并且可以工作,但窗口出现在屏幕的左上方。
#include <Xm/Form.h>
#include <Xm/Label.h>
#include <Xm/PushB.h>
void main ( int argc, char ** argv )
{
Widget shell, form, label, button;
XtAppContext app;
int i;
shell = XtAppInitialize ( &app, "Formtest", NULL, 0,
&argc, argv, NULL, NULL, 0 );
form = XtCreateManagedWidget ( "form", xmFormWidgetClass,
shell, NULL, 0 );
XtVaSetValues ( form,
XmNwidth, 500,
XmNheight, 300,
NULL );
label = XtVaCreateManagedWidget ( "label", xmLabelWidgetClass,
form, NULL, 0 );
button = XtVaCreateManagedWidget ( "button", xmPushButtonWidgetClass,
form,
XmNbottomAttachment, XmATTACH_FORM,
0 );
XtVaSetValues ( button,
XmNwidth, 100,
XmNheight, 50,
NULL );
XtRealizeWidget ( shell );
XtAppMainLoop ( app );
}`````
This MOTIF Windows is working correct already.
The only thing i want to do is to position it in the middle of the computerscreen.
It has something to do with the command Xtscreen.
