Top panel for deepin desktop environment v20.

This is a modification of dde-dock for top panel. Comparing to dde-dock, it:

• remove the launcher, show desktop, multi tasking, and application icons
• full support for dde-dock plugins and tray
• remove lots of unnecessary things so it is just a top panel. It is fixed to the top of the screen, and there is no way to change that.
• separate plugin config gsetting path /com/deepin/dde/toppanel
• different plugin directories: /usr/lib/dde-top-panel/plugins and ~/.local/lib/dde-top-panel/plugins

• global menu support (with dde-globalmenu-service)
• show window title on top panel
• show title buttons on top panel when current window maximized
• double click on empty area on top panel will maximize current window
• dragging and moving current maximized window by dragging empty area of top panel
• coping with ~/.config/kwinrc can remove the window title bar when maximized
• support multi monitors
• personal customization

Know issues:

• panels on non-primary monitors only have the window title function. The plugins can not work on them. It is not an issue because the QPluginLoader can only create one instance from one plugin file. So the panel cannot create as many plugin widgets as the panels. Still trying to add the plugin back to all panels
• Shortcuts of the global menu not work yet

• Always show title buttons for maxmized window and hide for unmaxminzed window (optional: show menu for maximized window on hover)
• Show window title only when no global menu for current window

1. download zip from release page and unzip it
2. cp *.xml to /usr/share/glib-2.0/schemas, and run sudo glib-compile-schemas /usr/share/glib-2.0/schemas
3. run ./dde-top-panel
4. for removing the title bar of maximized windows, make sure your ~/.config/kwinrc contains items below, then logout.

[Windows]
BorderlessMaximizedWindows=true

4. If you want to use plugins on top panel, just copy the plugin files to ~/.local/lib/dde-top-panel/plugins. For example, if you want to get tray icons on top panel, just cp /usr/lib/dde-dock/plugins/libtray.so ~/.local/lib/dde-top-panel/plugins
5. If you want to enable the global menu, please install !(dde-globalmenu-service)[https://github.com/SeptemberHX/dde-globalmenu-service.git]

Thanks to @JunioCalu . dde-top-panel is in the AUR now. https://aur.archlinux.org/packages/dde-top-panel

I only have deepin v20 installed on my computer, and I cannot compile it for other distributions. So it needs to be built from source.

Dependency: Qt5Widgets, Qt5Concurrent, Qt5X11Extras, Qt5DBus, Qt5Svg, DtkWidget, DtkCMake, KF5WindowSystem, XCB_EWMH, DFrameworkDBus, QGSettings, DtkGUI

git clone https://github.com/SeptemberHX/dde-top-panel.git
cd dde-top-panel
mkdir build
cd build
cmake ..
make

Then dde-top-panel should be in build/frame/dde-top-panel. Then go to step 2 in How to run for Deepin V20

Due to the logical of tray plugins, only one tray widget can hold the wine trays (You can click the icon and it will response to the click).

The main code of wine trays is in plugins/tray/xembedtraywidget. Generally, it wraps the raw wine trays with a new widget and embeds it to the tray, then it operates on the new widget. The problem is every tray widget will create a new container widget for each wine trays, and the tray widgets launched before can't the window id of the new container widget.

This part needs help.
