LayoutMdi fails in form's OnLoad event

由 不羁的心 提交于 2019-11-28 06:44:14
问题 Hello I have OnLoad eventhandler like this: private void MainView_Load(object sender, EventArgs e) { LayoutMdi(MdiLayout.TileVertical); } But nothing happens. How do I make it work? 回答1: Yes, doesn't work. Probably because the child windows aren't visible yet. It works fine in the Shown event: protected override void OnShown(EventArgs e) { var f2 = new Form2(); f2.MdiParent = this; f2.Show(); f2 = new Form2(); f2.MdiParent = this; f2.Show(); this.LayoutMdi(MdiLayout.TileVertical); } 回答2:

How to hide a MDI Child form in Delphi?

问题 How can I hide a MDIChild window in Delphi? I'm using this code in FormClose() event of my MDI children, but it doesn't seem to work: procedure TfrmInstrument.FormClose(Sender: TObject; var Action: TCloseAction); begin Action := caNone; ShowWindow(Handle, SW_HIDE); frmMainForm.MDIChildClosed(Handle); end; My child window is minimized instead of being hidden. 回答1: There is a protected procedure in TCustomForm defined as: procedure TCustomForm.VisibleChanging; begin if (FormStyle = fsMDIChild)

问题 I've got a strange problem adding a dll reference. I've got a WPF application and am trying to use the WPF MDI library: http://wpfmdi.codeplex.com/ As stated in the instructions (which are very vague), I right-clicked on references in VS2012, clicked on Add reference.. , clicked on Browse.. and added my dll which I downloaded. Next, I added the following line in the XAML of my window: xmlns:mdi="clr-namespace:WPF.MDI;assembly=WPF.MDI" as stated in the instructions. However, when trying to add

Controls in container form come over child form?

In a container form I have menu and buttons to open ther forms. Here I am facing a problem when I open any form these buttns and lables come over newly opened form. Please guide me how I can manage this issue? I want to open a new form and keep these container form's controls in back ground of it. Anaya Upadhyay I've also got the same problem. I got an alternative solution as described below: Insert a timer control I've added the controls in a panel container And did the following private void timer1_Tick(object sender, EventArgs e) { if ((int)MdiChildren.GetLength(0) > 0) { panel1.Visible =

Visually remove/disable close button from title bar .NET

由 和自甴很熟 提交于 2019-11-27 06:48:11
问题 I have been asked to remove or disable the close button from our VB .NET 2005 MDI application. There are no native properties on a form that allow you to grey out the close button so the user cannot close it, and I do not remember seeing anything in the form class that will allow me to do this. Is there perhaps an API call or some magical property to set or function to call in .NET 2005 or later to do this? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ More information: I need to maintain the minimize

Size/Location of Winforms MDI Client Area

由 ╄→гoц情女王★ 提交于 2019-11-27 05:55:21
问题 Inside an MDI form is a client area that hosts the mdi child forms. How do I find out how big that area is? The best I can come up with so far is finding the total size of the parent's potential client area (mdiparent.ClientRectangle) and then subtracting off the sizes of components like toolbars, etc that take away from the client area. Is there a better way? 回答1: There is no property on a form that gives you access to the MDI client window. But you can find it back like this: public
