拜托,您能帮我吗?如何创建更多相同外观的按钮。我在一个单独的类中有按钮的图形结构。用于创建我在Windows窗体中的按钮的功能。

步骤1) 图形按钮结构类:

class GraphicClassStructure : GraphicPosition
{
    public Button resetTree = new Button();

    public void CreateClassButtons()
    {
        // Reset tree
        resetTree.BackColor = Color.Transparent;
        resetTree.BackgroundImage = BuildResource.reset;
        resetTree.BackgroundImageLayout = ImageLayout.Stretch;
        resetTree.FlatAppearance.BorderSize = 0;
        resetTree.FlatAppearance.MouseDownBackColor = Color.Transparent;
        resetTree.FlatAppearance.MouseOverBackColor = Color.Transparent;
        resetTree.FlatStyle = FlatStyle.Flat;
        resetTree.Name = "resetTree";
        resetTree.Size = Size[0][5];
        resetTree.UseVisualStyleBackColor = false;
    }
}

控制按钮的Win表单功能。

private void classMenu_Click(object sender, EventArgs e)
{
    classStructure.ClassAllButtonsVisible();
    classStructure.CreateClassButtons();
    this.Controls.Add(classStructure.classBackround);

    for (int i = 0; i < 3; i++)
    {
        switch (i)
        {
            case 0:
                classStructure.resetTree.Location = classStructure.Location[0][2];
                break;
            case 1:
                classStructure.resetTree.Location = classStructure.Location[0][3];
                break;
            case 2:
                classStructure.resetTree.Location = classStructure.Location[0][4];
                break;
        }
        classStructure.resetTree.Click += new EventHandler(resetTreeOneEvent_Click);
        classStructure.resetTree.MouseEnter += new EventHandler(resetTree_MouseEnter);
        classStructure.resetTree.MouseLeave += new EventHandler(resetTree_MouseLeave);
        classStructure.resetTree.Tag = i;
        this.Controls.Add(classStructure.resetTree);
    }
}

当前的问题是按钮的创建在“GraphicStructure”类中,但在类中它只创建一个按钮。虽然我可以将windows形式嵌入到该功能中,但我想分别使用图形按钮和功能。你能帮我吗?。

控制:

private void resetTreeOneEvent_Click(object sender, EventArgs e)
{
    Button button = sender as Button;
    if (button != null)
    {
        switch ((int)button.Tag)
        {
            case 0:
                // First Button Clicked
                break;
            case 1:
                // Second Button Clicked
                break;
            case 2:
                // Third Button Clicked
                break;
        }
    }
}

或者第二个想法。我创建了一个什么都不做但没有图形结构的按钮。然后创建三个已经在做某事的额外按钮,但又没有图形,只需要让这些按钮做一些克隆的图形按钮,什么都不做。

我尝试使用此功能,但我仍然只看到一个按钮:

private void classMenu_Click(object sender, EventArgs e)
{
    classStructure.ClassAllButtonsVisible();
    classStructure.CreateClassButtons();
    this.Controls.Add(classStructure.classBackround);

    for (int i = 0; i < 3; i++)
    {
        Button button = new Button();
        button = classStructure.resetTree;
        switch (i)
        {
            case 0:
                button.Location = classStructure.Location[0][2];
                break;
            case 1:
                button.Location = classStructure.Location[0][3];
                break;
            case 2:
                button.Location = classStructure.Location[0][4];
                break;
        }
        button.Click += new EventHandler(resetTreeOneEvent_Click);
        button.MouseEnter += new EventHandler(resetTree_MouseEnter);
        button.MouseLeave += new EventHandler(resetTree_MouseLeave);
        button.Tag = i;
        this.Controls.Add(button);
    }
}

第二个想法工作(我看到三个按钮),如果我评论这个:

button = classStructure.resetTree;

但如果我评论这部分代码,那么所有三个按钮都没有图形结构。

如果您需要具有相同外观的按钮,请创建继承自Button的自定义按钮,并使用它而不是标准Button

public class TreeButton : Button
{
    public TreeButton()
    {
        BackColor = Color.Transparent;
        BackgroundImage = /* set some image  */
        BackgroundImageLayout = ImageLayout.Stretch;
        FlatAppearance.BorderSize = 0;
        FlatAppearance.MouseDownBackColor = Color.Transparent;
        FlatAppearance.MouseOverBackColor = Color.Transparent;
        FlatStyle = FlatStyle.Flat;       
        Size = /* set size */
        UseVisualStyleBackColor = false;
    }
}

如果您希望按钮的行为不同,请将不同的点击事件处理程序分配给不同的按钮。
