## Integrate

### Build & Install

```sh
cmake -B build \
  -Dqmsetup_DIR=<dir> \ # Optional
  -DCMAKE_INSTALL_PREFIX=/path/install \
  -G "Ninja Multi-Config"

cmake --build build --target install --config Debug
cmake --build build --target install --config Release
```

You can also include this directory as a sub-project if you choose CMake as your build system.

For other build systems, you need to install with CMake first and include the corresponding configuration files in your project.

### Import

#### CMake Project

```cmake
cmake -B build -DQWindowKit_DIR=/path/install/cmake/QWindowKit
```
```cmake
find_package(QWindowKit REQUIRED)
taraget_link_libraries(widgets_app PUBLIC QWindowKit::Widgets)
taraget_link_libraries(quick_app PUBLIC QWindowKit::Quick)
```

#### QMake Project
```cmake
# WidgetsApp.pro
include("/path/install/share/QWindowKit/qmake/QWKWidgets.pri")

# QuickApp.pro
include("/path/install/share/QWindowKit/qmake/QWKQuick.pri")
```

#### Visual Studio Project

## Quick Start

### Qt Widgets Application

First, setup `WidgetWindowAgent` for your QWidget instance. (Each widget needs its own agent.)

```c++
auto w = new MyWidget();
auto agent = new WidgetWindowAgent(w);
agent->setup(w);
```

You can also initialize the agent in the widget constructor.

```c++
MyWidget::MyWidget(QWidget *parent) {
    // ...
    auto agent = new WidgetWindowAgent(w);
    agent->setup(w);
}
```

Then, construct your titlebar widget, without which the window is lacking in basic interaction feature. You can use the [`WindowBar`](examples/shared/widgetframe/windowbar.h) provided by `WidgetFrame` in the examples as the container for your titlebar components.

```c++
auto titleLabel = new QLabel();
auto menuBar = new QMenuBar();

auto windowBar = new QWK::WindowBar();
windowBar->setMenuBar(menuBar);
windowBar->setTitleLabel(titleLabel);
windowBar->setHostWidget(this);

auto iconButton = new QPushButton("😄");
auto minButton = new QPushButton("─");
auto maxButton = new QPushButton("▢");
auto closeButton = new QPushButton("✕");
agent->setSystemButton(QWK::WindowAgentBase::WindowIcon, iconButton);
agent->setSystemButton(QWK::WindowAgentBase::Minimize, minButton);
agent->setSystemButton(QWK::WindowAgentBase::Maximize, maxButton);
agent->setSystemButton(QWK::WindowAgentBase::Close, closeButton);

```
