To create a mouse over button I use this code
private void btnCreateAccount_MouseHover(object sender, EventArgs e)
{
btnCreateAccount.ForeColor = Color.Gold;
}
private void btnCreateAccount_MouseLeave(object sender, EventArgs e)
{
btnCreateAccount.ForeColor = Color.Black;
}
The mouse over button works however when I hover over the button there is a good at least 1 second delay. I would think that it should change colour as soon as the mouse is placed over the button and not with a (in my opinion) too long delay.
Is there any way of fixing that code by like refreshing the button or something along those lines? or perhaps someone has a code that works perfectly?
You are handling the Mouse Hover event. This will require the cursor to be still for a short while in order to fire.
The pause required for this event to be raised is specified in milliseconds by the MouseHoverTime property.
This is read only.
Normally if you want the colour to change immediately you should handle the Mouse Enter event:
private void btnCreateAccount_MouseEnter(object sender, EventArgs e)
{
btnCreateAccount.ForeColor = Color.Gold;
}

The question is this:
when the mouse cursor moved on the button some thing should be happen but I don't know what exactly have to write
When you select the button in the VS-designer you will have access to the properties and events (lightning Icon in the property window).
In the events-listing are all events that the button can fire. May be for your purpose the events: ´MouseEnter´ and ´MouseLeave´ would be a good choice. Just double click the event and Visual Studio will generate the appropriate method. Like this:
private void button1_MouseEnter(object sender, EventArgs e)
{
// my code
this.button1.BackColor = Color.Red;
}
private void button1_MouseLeave(object sender, EventArgs e)
{
// my code
this.button1.BackColor = Color.Green;
}
In my example I just change the backcolour of the button when the mouse is on the button and change it again when it leaves the button.
Practically you could run any code inside the generated method.
You can create eventHandler like this :
myButton.MouseMove += new MouseEventHandler(doSomething);
Where myButton is the button from which you want to trigger the event when mouse moves over it. and doSomething() is the method defined as like the following:
public void doSomething(object sender, MouseEventArgs e)
{
// do what ever you want
}
Im working in WinForms I have 4 buttons on my form. I want to be able to hover my mouse over it and change the FlatStyle from Flat to System.
My code transforms all the buttons to System Style when you hover your mouse over it, that's not exactly what i had in mind.
All the buttons should remain flat until you hover over them. If you hover off the button it should turn back into flat button
private void All_Button_Hover_MouseHover(object sender, EventArgs e)
{
btn_Back.FlatStyle = FlatStyle.System;
Btn_Forward.FlatStyle = FlatStyle.System;
btn_Print.FlatStyle = FlatStyle.System;
btn_Open.FlatStyle = FlatStyle.System;
}
Here's a suggestion of how you could handle this.
You're already setting all the buttons in a single event method, which is fine. Since the button that triggered the event is stored in sender, you could just use that:
private void All_Button_Hover_MouseHover(object sender, EventArgs e)
{
((Button)sender).FlatStyle = FlatStyle.System;
}
To change the buttons back to the original FlatStyle.Flat style, you'll probably want to subscribe all of their MouseLeave events to a method as well:
private void All_Button_Hover_MouseLeave(object sender, EventArgs e)
{
((Button)sender).FlatStyle = FlatStyle.Flat;
}
I have a program that uses OpenTk.GLControl. Now on my listener, every time the mouse hovers to the said control, say "glControl1", I want to get the mouse coordinates.
Is that possible? sample code below.
private void glControl1_MouseHover(object sender, EventArgs e)
{
// get the current mouse coordinates
// .........
}
OpenTK.GLControl inherits from System.Windows.Forms.Control. You can use the following code snippet to get the mouse position:
private void glControl1_MouseHover(object sender, EventArgs e)
{
Control control = sender as Control;
Point pt = control.PointToClient(Control.MousePosition);
}
Please refer to the MSDN WinForms documentation for more information.
The problem is that you're using the wrong event. Many UI actions in WinForms trigger multiple events per action; Hover is used for things like popping up tooltips. You don't get a coordinate in Hover because it's unnecessary.
What you want is the MouseMove event. This is used to track the mouse position:
private void glControl1_MouseMove(object sender, MouseEventArgs e)
{
foo = e.X;
bar = e.Y;
}
I dont know, what is OpenTk.GLControl, but:
I was handling swipe events on Windows Phone and did this:
private void PhoneApplicationPage_MouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
//string to save coordinates of tap
TapCoordinatesXBegin = e.GetPosition(LayoutRoot).X.ToString();
TapCoordinatesYBegin = e.GetPosition(LayoutRoot).Y.ToString();
}
And i dont remember such event MouseHover - maybe MouseEnter?
I have the following problem: I have a panel which has a specific color, say red.
When the user presses his mouse, the color of this panel gets stored in a variable. Then the user moves, his mouse still pressed, over to another panel. When he releases the mouse there, this panel should get the background color of the first that had been stored in the variable. My code looks something like this:
public Color currentColor;
private void ColorPickMouseDown(object sender, MouseEventArgs e)
{
Panel pnlSender = (Panel)sender;
currentColor = pnlSender.BackColor;
}
private void AttempsColorChanger(object sender, MouseEventArgs e)
{
Panel pnl = (Panel)sender;
pnl.BackColor = currentColor;
}
I need to identify the sender first because there are many possible panels that can trigger this event. The first MouseDown method works totally fine, the color is stored nicely in the variable. The secon one however doesn't even get triggered when the user does what I described above. When the ser clicks on the second panel, it works (there is an MouseUp part in a click aswell I guess).
What's wrong here? Why is the event not triggered when the user holds the mouse key down before?
(This answer assumes you are using Windows Forms.)
It could be that you need to capture the mouse by setting this.Capture = true in the MouseDown of the source control. (See Control.Capture)
If you did that, the source window would get the MouseUp event, and it would be the source window that had to determine the destination window under the mouse coords. You can do that using Control.GetChildAtPoint() (see this answer on Stack Overflow).
Use Windows Forms Drag and Drop Support Instead! <- Click for more info
I'm going to suggest you bite the bullet and use the .Net Drag and Drop methods to do this. It requires some reading up, but it will be much better to use it.
You start a drag in response to a MouseDown event by calling Control.DoDragDrop().
Then you need to handle the Control.DragDrop event in the drop target control.
There's a few more things you might need to do to set it up; see the Control.DoDragDrop() documentation for an example.
(For WPF drag and drop support, see here.)
when your mouse enter the target control , mouse down triggerd ang get target BackColor! you need add an boolean flag to your code :
public Color currentColor;
bool flag=false;
private void ColorPickMouseDown(object sender, MouseEventArgs e)
{
if(flag==false)
{
flag=true
Panel pnlSender = (Panel)sender;
currentColor = pnlSender.BackColor;
}
}
//assume mouse up for panles
private void AttempsColorChanger(object sender, MouseEventArgs e)
{
if(flag==true)
{
Panel pnl = (Panel)sender;
pnl.BackColor = currentColor;
flag=flase;
}
}
and also you need change your flag in mouseMove( if )
As I mentioned in my comment Mouse Events are captured by the originating control, You would probably be better off using the DragDrop functionality built into Windows Forms. Something like this should work for you. I assigned common event handlers, so they can be assigned to all of your panels and just work.
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void panel_MouseDown(object sender, MouseEventArgs e)
{
((Control)sender).DoDragDrop(((Control)sender).BackColor,DragDropEffects.All);
}
private void panel_DragDrop(object sender, DragEventArgs e)
{
((Control)sender).BackColor = (Color)e.Data.GetData(BackColor.GetType());
}
private void panel_DragEnter(object sender, DragEventArgs e)
{
e.Effect = DragDropEffects.Copy;
}
}
I know it's an old question but I had the same issue and none of the above answers worked for me. In my case I had to handle the MouseMove event in the target control and check for the mouse to be released. I did set 'BringToFront' on my target panel just in case that helped at all.
public Color currentColor;
private void ColorPickMouseDown(object sender, MouseEventArgs e)
{
Panel pnlSender = (Panel)sender;
currentColor = pnlSender.BackColor;
}
private void panelTarget_MouseMove(object sender, MouseEventArgs e)
{
//the mouse button is released
if (SortMouseLocation == Point.Empty)
{
Panel pnl = (Panel)sender;
pnl.BackColor = currentColor;
}
}
Have a simple form that has a PictureBox in one location. I want to change the cursor to the Cross cursor when entering that control, and change it back when it leaves.
private void Canvas_MouseEnter(object sender, EventArgs e)
{
this.Canvas.Cursor = Cursors.Cross;
}
private void Canvas_MouseLeave(object sender, EventArgs e)
{
this.Canvas.Cursor = Cursors.Default;
}
This doesn't work. If I look closely, I can see it quickly change on MouseEnter, but it flips right back to the default cursor. I have to add "this.Canvas.Cursor = Cursors.Cross;" to the MouseMove event in order for it to work, but then I can constantly see it flickering back to the default cursor.
What gives? This is the only cursor-related code in my whole application, what would be causing it to reset to the default cursor every time I move the mouse?
Thanks.
EDIT: I am an idiot. Person I am collaborating with on this little app had some cursor code tucked away somewhere else that was causing the problem. Thanks guys.
Why don't you set the cursor for the picturebox?
yourPictureBox.Cursor = Cursors.Cross;
I've tried in a new project from scratch (with just the mouseenter/leave handlers and nothing else) and it works.
Might be something else in your application ?
public Form1()
{
InitializeComponent();
pictureBox1.MouseHover += new EventHandler(PictureBox1_MouseHover);
}
void pictureBox1_MouseHover(object sender, EventArgs e)
{
this.PictureBox1.Cursor = Cursors.Cross;
}
You want to use MouseHover event handler.
