Is it possible to show MainMenu in full screen?

[Guest ronswens]

I have full screen app so to delete soft keys I set Menu to null. But I still need to show MainMenu by pressing right soft key. Is it possible?

Yepps... That's possible: You need to capture the keypress from the Form, and then (re)-assign the Mainmenu1 to menu if the right key (F2) is pressed.

Thanks for asnwer edgecrush3r,

but I'm afraid I was inaccurate in my question. I'll explain. I have 2 states of my app - full-screen mode and window-screen mode with the menu with several commands. What I want is in the full-screen mode after pressing a right soft-key the menu with commands appears just like it appears after pressing right soft-key in the window-screen mode. And the menu disappears after chosing any command from the menu and I get right to full-screen mode. Is it still possible?

Ofcourse.. The example did half of the job already..

If you want to hide the menu again after the selection, just use: this.Menu = null; again after you have invoked your menuItem_event.

Here's the code:

using System;

using System.Drawing;

private System.Windows.Forms.MenuItem menuItem4;

private System.Windows.Forms.MainMenu mainMenu1;

So I need to insert "this.Menu = null;" in every click command handler? Ok, I guessed there's no other way but how to get rid of double press of F2 (a right soft key) to show the command list? I must press it once to mainmenu appears and second time to show the command list. Is there a way to show the list right after F2 was pressed for the first time?

Yupps... Removing Items from the MainMenu collection is not supported on the Smartphone device, therefore theres no other way than disposing, and re-assigning.. Ofcourse you can easily create a more versatile control by extending the MainMenu class, and assign the collection to a temp menuItemCollection..

On the second question,.. Did you try to fire the Popup event manually ?

No, I don't know how. I know that I can show ContextMenu using ContextMenu.Show but then I need to have a control to bind a ContextMenu to it. But how to show MainMenu?

Seems that this popup-behaviour cannot be implemented using the MainMenu, and thus you will be stuck pressing F2 twice. If you found a way.. let me know :D

[Guest ronswens]

Only if use P/Invoke to keybd_event(), I hate this. Thanks for help edgecrush3r :D

Not the must elegan t way indeed, but heY if it works, it works !!... Can you share the interop code with us please ?

Thanks,

[Guest ronswens]

Sure!

[system.Runtime.InteropServices.DllImport("coredll.dll")]

private static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);

const int VK_F2 = 0x71;

protected override void onkeydown(KeyEventArgs e)

{

switch(e.KeyCode)

{

case Keys.F2:

//Quit full-screen

WindowState = FormWindowState.Normal;

FormBorderStyle = FormBorderStyle.Sizable;

Menu = menu;

//Send right soft key press and release

keybd_event(VK_F2,0, 0, 0);

keybd_event(VK_F2,0, 2, 0);

break;

}

}
