I've main form when I press btn I open new form with showDialog() function, I need to move two forms together when I press on main form, because they share in design. how can I move them together either I press on main form and move it or I press on for开发者_JAVA百科m2 and move it? Thx alot for any suggestion.
You could create a separate class to manage the form connections and event handling.
class FormConnector
{
private Form mMainForm;
private List<Form> mConnectedForms = new List<Form>();
private Point mMainLocation;
public FormConnector(Form mainForm)
{
this.mMainForm = mainForm;
this.mMainLocation = new Point(this.mMainForm.Location.X, this.mMainForm.Location.Y);
this.mMainForm.LocationChanged += new EventHandler(MainForm_LocationChanged);
}
public void ConnectForm(Form form)
{
if (!this.mConnectedForms.Contains(form))
{
this.mConnectedForms.Add(form);
}
}
void MainForm_LocationChanged(object sender, EventArgs e)
{
Point relativeChange = new Point(this.mMainForm.Location.X - this.mMainLocation.X, this.mMainForm.Location.Y - this.mMainLocation.Y);
foreach (Form form in this.mConnectedForms)
{
form.Location = new Point(form.Location.X + relativeChange.X, form.Location.Y + relativeChange.Y);
}
this.mMainLocation = new Point(this.mMainForm.Location.X, this.mMainForm.Location.Y);
}
}
Now all you have to do is to instantiate a FormConnector and call ConnectForm method with the form you want to connect to.
The main ingredients are the forms' Top
, Left
, Location
, and Width
properties. Say you have a reference to both forms, called form1
and form2
. You could reposition windows like so:
form2.Location = new Point(form1.Left + form1.Width, form1.Top);
The result is both forms, top aligned, with form2 on the right.
