GLFW: Moving from GLFW 2 to 3 より

• /dev/sda1 Windows Vista用の何か
• /dev/sda2 Windows Vista 約160GB
• /dev/sda3 拡張パーティション
• /dev/sda5 Linux Mint 約50GB
• /dev/sda6 Linux swap

• Windows Vista用のパーティションを160GBから120GBにリサイズ(縮小)。
• 40GBほど空き領域ができるので、拡張パーティションの先端を前にずらす。
• Linux Mint 用パーティションと Linux swap も前に移動した。移動する際、「この処理をするとOSがブートできなくなるよ」と警告が出てきたけど、そのまま作業を進めた。

2. その FXPacker に、FXHorizontalFrame (部品を横並びにしてくれる) や FXVerticalFrame (部品を縦並びにしてくれる) 等のフレームを登録。
3. それらフレームに、各部品を登録。
