保持应用程序窗口总是在当前桌面上的linux和mac [英] Keep a application window always on current desktop on linux and mac
问题描述
我搜索一种方式,将Qt应用程序的QWidget窗口始终放在当前桌面/工作区上。
当我更改虚拟桌面时,我需要在新的当前虚拟桌面上自动显示我的窗口。
我搜索一个解决方案, gnome,kde on linux和mac os。
我认为第一步是检测虚拟桌面是否发生变化,我不知道Qt是否有API
预先感谢所有帮助。

针对linux X11的解决方案:
#ifdef Q_WS_X11 //只定义Qt 4.X
#include< QX11Info> //只在Qt 4.X,返回预期在Qt 5.1
#include< X11 / Xlib.h>
#include< X11 / Xatom.h>
#endif
YourWidget :: YourWidget(QWidget * parent):
QWidget(parent),
ui(new Ui :: YourWidget)
{
#ifdef Q_WS_X11 //只定义Qt 4.X
无符号长数据= 0xFFFFFFFF;
XChangeProperty(QX11Info :: display(),
winId(),
XInternAtom(QX11Info :: display(),_NET_WM_DESKTOP,False),
XA_CARDINAL,
32,
PropModeReplace,
reinterpret_cast< unsigned char *>(& data),//所有桌面
1);
#endif
}
unix:!macx {
LIBS + = -lX11
}
macos X的解决方案:
#include< ; objc / objc-runtime.h>
WId windowObject = this-> winId();
objc_object * nsviewObject = reinterpret_cast< objc_object *>(windowObject);
objc_object * nsWindowObject = objc_msgSend(nsviewObject,sel_registerName(window));
int NSWindowCollectionBehaviorCanJoinAllSpaces = 1<< 0;
objc_msgSend(nsWindowObject,sel_registerName(setCollectionBehavior:),NSWindowCollectionBehaviorCanJoinAllSpaces);
将这个放在您的.pro
macx {
LIBS + = -lobjc
}
I search a way to put a QWidget window of a Qt application always on the current desktop/workspace. When I change the virtual desktop, I need my window to be automatically visible on the new current virtual desktop.
I search a solution that works at minimum on gnome, kde on linux and mac os.
I think the first step is to detect when virtual desktop is change, I don't know if Qt have a API for that or if I need to implement it for each desktop solution.
Thanks in advance for all help.
解决方案Thanks to Jan Kundrát for his help (Previous comment http://stackoverflow.com/a/16777496/1045832 ).
Solution for linux X11 :
#ifdef Q_WS_X11 //only define on Qt 4.X #include <QX11Info> //Only on Qt 4.X , return expected in Qt 5.1 #include <X11/Xlib.h> #include <X11/Xatom.h> #endif YourWidget::YourWidget(QWidget *parent) : QWidget(parent), ui(new Ui::YourWidget) { #ifdef Q_WS_X11 //only define on Qt 4.X unsigned long data = 0xFFFFFFFF; XChangeProperty (QX11Info::display(), winId(), XInternAtom(QX11Info::display(), "_NET_WM_DESKTOP", False), XA_CARDINAL, 32, PropModeReplace, reinterpret_cast<unsigned char *>(&data), // all desktop 1); #endif }
Put this on your .pro
unix:!macx { LIBS += -lX11 }
Solution for macos X :
#include <objc/objc-runtime.h> WId windowObject = this->winId(); objc_object * nsviewObject = reinterpret_cast<objc_object *>(windowObject); objc_object * nsWindowObject = objc_msgSend(nsviewObject, sel_registerName("window")); int NSWindowCollectionBehaviorCanJoinAllSpaces = 1 << 0; objc_msgSend(nsWindowObject, sel_registerName("setCollectionBehavior:"), NSWindowCollectionBehaviorCanJoinAllSpaces);
Put this on your .pro
macx { LIBS += -lobjc }
