Delphi StringGridコンポーネント大全

前回のセッションで 1 次元配列と 2 次元配列に関するすべてを学び、これらの配列が Delphi の Windowsアプリケーション開発でどのように使用されているかを学習したので、次はこれらの知識をすべてまとめて優れたアプリケーションを作成します。このビデオでは、Aubrey Pule Khoza が、表形式のデータと Delphi の StringGrid コンポーネントについて説明します。最近開催された Coding Boot Camp 2022 では、 Forループ, 配列、そして文字列の使用など、ここで学んだことを活かしてアプリケーション作成に挑みます。

What do you need to know about the StringGrid component?

When talking about tabular data or data represented in table form, some of you might be thinking of the two-dimensional arrays that were further elaborated from the previous sessions. These arrays are actually relevant or strongly related if you are using StringGrid. The session will highlight some of the most important procedures and functions for text files including AssignFile, Append, Rewrite, Reset, Read, and more.

So, what is a StringGrid component? The StringGrid component is generally described as a visual representation of a grid that consists of rows and columns. It can also be seen as a visual version of a two-dimensional array. The StringGrid component can be found underneath the Additional Tab on the Component Palette. When you index the StringGrid, it is more like the same way you would index a two-dimensional array. The session will also discuss some of the StringGrid properties in the Object Inspector in Delphi including ColCount, RowCount, FixedRow, and ScrollBars to name a few.

To understand more about how the StringGrid component works, Aubrey will demonstrate a sample application named Music Delphi that shows how this component is used. He also discusses some of the other things you can do to expand the app’s functionality. Feel free to watch the video below to learn more.
