Gets a system-defined color.
Assembly: System.Drawing (in System.Drawing.dll)
The following code example demonstrates how to use the Transparent property. This example is designed to be used with Windows Forms. Paste the code into a form that contains two buttons named Button1 and Button2. Call the UseTransparentProperty method in the form's constructor.
private: void UseTransparentProperty() { // Set up the PictureBox to display the entire image, and // to cover the entire client area. PictureBox1->SizeMode = PictureBoxSizeMode::StretchImage; PictureBox1->Dock = DockStyle::Fill; try { // Set the Image property of the PictureBox to an image retrieved // from the file system. PictureBox1->Image = Image::FromFile( "C:\\Documents and Settings\\All Users\\" "Documents\\My Pictures\\Sample Pictures\\sunset.jpg" ); // Set the Parent property of Button1 and Button2 to the // PictureBox. Button1->Parent = PictureBox1; Button2->Parent = PictureBox1; // Set the Color property of both buttons to transparent. // With this setting the buttons assume the color of their // parent. Button1->BackColor = Color::Transparent; Button2->BackColor = Color::Transparent; } catch ( System::IO::FileNotFoundException^ ) { MessageBox::Show( "There was an error." "Make sure the image file path is valid." ); } }
