TableLayoutPanel中的缩放控制

Question

为什么tableLayoutPanel.Dock = DockStyle.Fill;不起作用，tableLayoutPanel不能填满Form中的所有可用空间

如何扩展button.Text = "Button";

namespace Scalability
{
    static class Program
    {
        /// <summary>
        /// Главная точка входа для приложения.
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            ViewForm viewForm = new ViewForm();
            Application.Run(viewForm);
        }
    }
}

namespace Scalability.Forms
{
    class ViewForm:Form
    {
        public ViewForm()
        {
            TableLayoutPanel tableLayoutPanel = new TableLayoutPanel();
            Button button = new Button();
            button.Text = "Button";
            button.Dock = DockStyle.Fill;

            Label label = new Label();
            label.Text="Label";
            label.Dock = DockStyle.Fill;

            TextBox textBox = new TextBox();
            textBox.Text = "textBox";
            textBox.Dock = DockStyle.Fill;

            tableLayoutPanel.Controls.Add(button, 0, 0);
            tableLayoutPanel.Controls.Add(label, 0, 1);
            tableLayoutPanel.Controls.Add(textBox, 1, 0);
            tableLayoutPanel.Dock = DockStyle.Fill;

            this.Controls.Add(tableLayoutPanel);
        }
    }
}

Answer 1

配置TableLayoutPanel的RowStyles，使其伸展

TableLayoutPanel tableLayoutPanel = new TableLayoutPanel();
tableLayoutPanel.RowStyles.Add(new RowStyle(SizeType.Percent, 50));
tableLayoutPanel.RowStyles.Add(new RowStyle(SizeType.Percent, 50));

但它确实起作用了。:)

1)尝试将颜色附加到控件，如下所示。

Button button = new Button();
button.Text = "Button";
button.BackColor = Color.Orange;
button.Dock = DockStyle.Fill;

Label label = new Label();
label.Text = "Label";
label.BackColor = Color.Yellow;
label.Dock = DockStyle.Fill;

TextBox textBox = new TextBox();
textBox.Text = "textBox";
textBox.BackColor = Color.Green;
textBox.Dock = DockStyle.Fill;

现在，您将看到这些控件完全按照您放置的方式使用整个窗口。所以按钮是列0，行0(左，上)。文本框为第1列，第0行(右上角)。标签为第0列，第1行(左下)。并且在第一列第一行中没有任何内容(右下角的“中心位置”是空的)。

如果你将一个按钮添加到1,1，它将在剩余的空间中伸展。像这样

// Blue button.
Button bbutton = new Button();
bbutton.Text = "Button";
bbutton.BackColor = Color.Blue;
bbutton.Dock = DockStyle.Fill;

tableLayoutPanel.Controls.Add(button, 0, 0);
tableLayoutPanel.Controls.Add(label, 0, 1);
tableLayoutPanel.Controls.Add(textBox, 1, 0);
// We added this one.
tableLayoutPanel.Controls.Add(bbutton, 1, 1);
tableLayoutPanel.Dock = DockStyle.Fill;

现在你就知道了。
