# [window+](https://github.com/alexmercerind/window_plus)
> Work in progress. API may change.
As it should be. Extend view into title-bar.
## Setup
Following configuration is required.
### macOS
Edit `macos/Runner/MainFlutterWindow.swift` as:
```diff
import Cocoa
import FlutterMacOS
+import window_plus
class MainFlutterWindow: NSWindow {
override func awakeFromNib() {
WindowPlusPlugin.handleSingleInstance()
let flutterViewController = FlutterViewController()
let windowFrame = self.frame
self.contentViewController = flutterViewController
self.setFrame(windowFrame, display: true)
RegisterGeneratedPlugins(registry: flutterViewController)
super.awakeFromNib()
}
+ override public func order(_ place: NSWindow.OrderingMode, relativeTo otherWin: Int) {
+ super.order(place, relativeTo: otherWin)
+ WindowPlusPlugin.hideUntilReady()
+ }
}
```
### Windows
Edit `windows/runner/win32_window.cpp` as:
```diff
HWND window = CreateWindow(
- window_class, title.c_str(), WS_OVERLAPPEDWINDOW | WS_VISIBLE,
+ window_class, title.c_str(), WS_OVERLAPPEDWINDOW,
Scale(origin.x, scale_factor), Scale(origin.y, scale_factor),
Scale(size.width, scale_factor), Scale(size.height, scale_factor),
nullptr, nullptr, GetModuleHandle(nullptr), this);
```
```diff
- case WM_SIZE: {
- RECT rect = GetClientArea();
- if (child_content_ != nullptr) {
- // Size and position the child window.
- MoveWindow(child_content_, rect.left, rect.top, rect.right - rect.left,
- rect.bottom - rect.top, TRUE);
- }
- return 0;
- }
case WM_ACTIVATE:
```
### Linux
Edit `linux/my_application.cc` as:
```diff
FlView* view = fl_view_new(project);
gtk_widget_show(GTK_WIDGET(view));
gtk_container_add(GTK_CONTAINER(window), GTK_WIDGET(view));
fl_register_plugins(FL_PLUGIN_REGISTRY(view));
- gtk_widget_grab_focus(GTK_WIDGET(view));
+ gtk_widget_hide(GTK_WIDGET(window));
```
## Single Instance
For enabling single instance support, follow the steps below.
### macOS
No changes required.
### Windows
In `windows/runner/main.cpp`, add the following code:
```diff
#include
#include
#include
#include "flutter_window.h"
#include "utils.h"
+ #include "window_plus/window_plus_plugin_c_api.h"
int APIENTRY wWinMain(_In_ HINSTANCE instance, _In_opt_ HINSTANCE prev,
_In_ wchar_t* command_line, _In_ int show_command) {
+ ::WindowPlusPluginCApiHandleSingleInstance(NULL, NULL);
// Attach to console when present (e.g., 'flutter run') or create a
// new console when running with a debugger.
if (!::AttachConsole(ATTACH_PARENT_PROCESS) && ::IsDebuggerPresent()) {
CreateAndAttachConsole();
}
```
If you use custom window class name, then you can pass it as the first argument instead of `NULL`. Similarly, if you want to also account for your window's title, then you can pass it as the second argument instead of `NULL`.
### Linux
You need to edit your `linux/my_application.cc` file. See [this file for reference](https://github.com/alexmercerind/window_plus/blob/master/example/linux/my_application.cc).
Notice how `G_APPLICATION_HANDLES_OPEN` & `G_APPLICATION_HANDLES_COMMAND_LINE` [are implemented](https://github.com/alexmercerind/window_plus/blob/562407f7f316714024577ce5467a12ee8f99bc24/example/linux/my_application.cc#L135-L149).
Finally, forward the arguments to Dart / Flutter, with [`window_plus_plugin_handle_single_instance` call at the required location](https://github.com/alexmercerind/window_plus/blob/562407f7f316714024577ce5467a12ee8f99bc24/example/linux/my_application.cc#L24-L31).
