I've created a simple program and now i'm in the stages of doing my designing. I've got a multiple Panels which i make visible / invisible to switch between "tabs" (EG. 1 panel for the login screen and 1 panel for the create account screen). Now i've made these panels invisible because i want them just as containers to be able to quickly move around controls and create buttons in.
My problem is that i've set my forms background image to a image i made in photoshop and whenever i switch between panels it flickers, whenever i just use a system color (white,black) this doesn't happen. Is there any way for me to remove the flickering?
i've tried :
my code is extremely basic :
private void btnNewAcc_Click(object sender, EventArgs e)
{
PanelNewAccount.Visible = true;
PanelLogin.Visible = false;
}
尝试将表单属性 DoubleBuffered 设置为 true,在 winforms 中通常会发生闪烁,因为 GDI+ 多次尝试绘制控件,因此在这种情况下,对图形进行双缓冲应该会有所帮助
form.DoubleBuffered = true;
Thanks to Patrick i've solved my problem, instead of using panels i'm using a TabControl and i assigned the same background to each tab. Just as easy to add dynamic buttons as well. Same features as panels but without the flickering.
#region .. Double Buffered function ..
public static void SetDoubleBuffered(System.Windows.Forms.Control c)
{
if (System.Windows.Forms.SystemInformation.TerminalServerSession)
return;
System.Reflection.PropertyInfo aProp = typeof(System.Windows.Forms.Control).GetProperty("DoubleBuffered", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
aProp.SetValue(c, true, null);
}
#endregion
#region .. code for Flucuring ..
protected override CreateParams CreateParams
{
get
{
CreateParams cp = base.CreateParams;
cp.ExStyle |= 0x02000000;
return cp;
}
}
#endregion
Even though i am late but if somebody else is also suffering from the same problem then this code fixed the flickering for me even though i dont know how it works. I found it here . Add the above code snippet in your program and in the contructor of your app add this line:
SetDoubleBuffered(YourPanelName);
protected override CreateParams CreateParams {
get {
CreateParams cp = base.CreateParams;
cp.ExStyle |= 0x02000000;
return cp;
}
}
code copy from codeproject solved my problem.
