为布尔按钮加载各种图像
本文关键字:图像 加载 布尔 按钮 | 更新日期: 2023-09-27 18:17:53
我在运行时创建按钮,我想为每个值true和false添加一个图像,如果我有onOff按钮,true为绿色,false为红色。
我的问题是1. 如何加载图片以最适合此目的?2. 如何以正确的方式创建按钮?3.我使用相同的功能枚举按钮,如果它看起来很奇怪。4. 我敢肯定我做错了很多事,请指教。foreach(p in properties){
if(p is bool){createBoolButton(p);}
//so on
string path;
string path2;
private Control createBoolButton(IProperty p) {
countControls2 = 1;
locationY = 10;
int gbHeight = 2;
radioButtonY = 10;
IType pType = p.Type;
var myP = new MyProperty(p, this);
if (myP.Value != null) {
}
Panel gb = new Panel();
gb.Location = new Point(locationY, nextLocationX);
nextLocationX += rbWidth + 10;
gb.Name = "groupBox" + p.Id;
gb.Text = p.Id;
gb.Tag = p;
bool[] x = { true, false };
foreach (var t in x) {
RadioButton rb = new RadioButton();
rb.Appearance = Appearance.Button;
rb.Width = rbWidth;
rb.Height = rbHeight;
rb.Name = t.ToString();
rb.Text = t.ToString();
rb.Tag = t;
countControls++;
rb.Location = new Point(radioButtonY, radioButtonX);
if (myP.Value != null && myP.Value.ToString().SafeEquals(rb.Text)) {
rb.Checked = true;
}
radioButtonY += rbHeight;
gb.Controls.Add(rb);
rb.CheckedChanged += rb_CheckedChanged;
}
gb.Width = rbHeight * gbHeight + 20;
gb.Height = rbWidth + 10;
Controls.Add(gb);
countControls2++;
return gb;
}
private void getimagesPath(EnumValue[] TypesArray) {
foreach (var enumType in TypesArray) {
string path = @"C:'Folder'" + enumType.Name + ".png";
string path2 = @"C:'Folder'" + enumType.Name + "_checked.png";
FileInfo fi = new FileInfo(path);
FileInfo fi2 = new FileInfo(path2);
if (!imagePaths.ContainsKey(enumType.Name) && !imagePaths.ContainsKey(enumType.Name + "_checked")) {
if (fi.Exists && fi2.Exists) {
imagePaths.Add(enumType.Name, path);
imagePaths.Add(enumType.Name + "_checked", path2);
}
}
else {
if (!imagePaths.ContainsKey(enumType.Name)) {
imagePaths.Add(enumType.Name, DEFAULT_IMAGE_PATH);
}
}
}
}
您应该将checked image
和unchecked image
保存为项目中的Resources
。只要查看Solution Explorer
,您将看到在项目节点下的Properties
节点下有一个Resources
节点。双击该节点,您应该知道如何向该Resources
添加图像。一旦向其中添加了图像,就可以轻松访问这些图像,如下面的代码所示。我假设您选中的图像被添加到名称为CheckedImage
的Resources
和未选中的图像被添加到名称为UncheckedImage
的Resources
:
//Here is your RadioButton CheckedChanged event handler to change to image accordingly.
private void rb_CheckedChanged(object sender, EventArgs e){
RadioButton button = sender as RadioButton;
button.Image = button.Checked ? Properties.Resources.CheckedImage : Properties.Resources.UncheckedImage;
}

我想在这种情况下你不需要图片。

创建按钮示例代码:
Dim pnl as new Panel Dim btn as new Button btn.Name = "btn1" btn.Location = new Point(..., ...) pnl.Controls.Add(btn)
