注釈

フォームの境界線のスタイルは、フォームの外側のエッジの表示方法を決定します。The border style of the form determines how the outer edge of the form appears. フォームの境界線の表示を変更するだけでなく特定の罫線のスタイルは、フォームを防ぐため、サイズを変更するから。In addition to changing the border display for a form, certain border styles prevent the form from being sized. たとえば、FormBorderStyle.FixedDialog境界線のスタイル ダイアログ ボックスのフォームの境界線を変更して、フォームがサイズを変更することを防ぎます。For example, the FormBorderStyle.FixedDialog border style changes the border of the form to that of a dialog box and prevents the form from being resized. 罫線のスタイルは、サイズやフォームのキャプション バーのセクションの可用性にも影響します。The border style can also affect the size or availability of the caption bar section of a form.

注意

Sizableスタイルは特定の最小値の下のウィンドウのサイズを変更する設定した場合でもControlBoxfalseに長さ 0 の文字列が割り当てられているとTextします。With the Sizable style, it is impossible to resize the window below a certain minimum value, even if you have set ControlBox to false and assigned a zero-length string to Text. 使用してこの問題を回避の作業を検討してください、SizableToolWindow代わりにスタイルを設定します。Consider working around this by using the SizableToolWindow style instead.
