Method popupMenu.Submenu(+ 1 overload)

Overload

Adds menu item that opens a submenu. Used like m.Submenu("Example", m => { /* add submenu items */ });.

public PMItem Submenu(string text, Action<popupMenu> opening, MTImage image = default, bool disable = false, int l_ = 0, string f_ = null)
Parameters
text  (string)

Item text. Can include hotkey, tooltip and underlined character, like "Te&xt\t Hotkey\0 Tooltip"; more info: popupMenu.
opening  (Action<popupMenu>)

Action called whenever opening the submenu and should add items to it.
image  (MTImage)

Item image. Read here: MTBase.
disable  (bool)

Disabled state.
l_  (int)
f_  (string)
Returns
PMItem

Remarks

The submenu is other popupMenu object. It inherits many properties of this menu; see property documentation.

Examples

m.Submenu("Example", m => {
	m["A"] = o => { print.it(o); };
	m["B"] = o => { print.it(o); };
});

This code shows dynamically created menu of files in a folder and subfolders. Subfolder files are retrieved when opening the submenu.

var m=new popupMenu();
_Dir(m, new DirectoryInfo(@"C:\"));
m.Show();

static void _Dir(popupMenu m, DirectoryInfo dir) {
	foreach (var v in dir.EnumerateFileSystemInfos()) {
		if(v.Attributes.Has(FileAttributes.System|FileAttributes.Hidden)) continue;
		if(v.Attributes.Has(FileAttributes.Directory)) {
			m.Submenu(v.Name, m=> _Dir(m, v as DirectoryInfo));
		} else {
			m[v.Name]=o=>print.it(v.FullName);
		}
		m.Last.File = v.FullName;
	}
}

Overload(top)

Adds menu item that opens a reusable submenu.

public PMItem Submenu(string text, Func<popupMenu> opening, MTImage image = default, bool disable = false, int l_ = 0, string f_ = null)
Parameters
text  (string)

Item text. Can include hotkey, tooltip and underlined character, like "Te&xt\t Hotkey\0 Tooltip"; more info: popupMenu.
opening  (Func<popupMenu>)

Func called whenever opening the submenu and should return the submenu object. Can return null.
image  (MTImage)

Item image. Read here: MTBase.
disable  (bool)

Disabled state.
l_  (int)
f_  (string)
Returns
PMItem

Remarks

The caller creates the submenu (creates the popupMenu object and adds items) and can reuse it many times. Other overload does not allow to create popupMenu and reuse same object. The submenu does not inherit properties of this menu.

Examples

var m2 = new popupMenu(); m2.AddCheck("C1"); m2.AddCheck("C2");
m.Submenu("Submenu", () => m2);
