An MFC Menu
1 Questions about the menu
Win32--hmenu
MFC----CMenu Class Object------Map for menu handle
The CMenu class encapsulates the various API functions of the Action menu
Encapsulates a member Cmenu::m_hmenu save menu Handle
2. Menu Usage
1. Add a menu Resource
2. Set the menu to the window
1) in the WM_CREATE message of the Frame class window
CMenu menu;
Menu. LoadMenu
Cframewnd::setmenu--Set the menu to the window

2) in the CFrameWnd::Create parameter settings menu

3. Handling of menu item messages (WM_COMMAND)
Frame processing the app does not handle frame precedence over app processing, determined by cframewnd::oncmdmsg internal code execution sequencing
4. Setting Menu state
On_wm_initmenupopup
Checkmenuitem EnableMenuItem
3. Right-click menu
On_wm_contextmenu
Cmenu::getsubmenu get a drop-down menu for a top-level menu

Windows standard messages, frequently used, typically on_wm_xxx () macros
Two toolbars
1, toolbar related classes
CToolBarCtrl-The parent class is CWnd, encapsulating API functions for various operations on Toolbarctrl.
CFrameWnd is equivalent to a container that contains various windows inside. child window, docking relationship,
CToolbar-The parent class is CControlBar, encapsulates the relationship between toolbars and frame windows, and also includes the creation of toolbars

2. Use of toolbars
1. Add Toolbar resources
2. Create a toolbar Ctoolbar::create/createex
3. Load the toolbar resource Ctoolbar::loadtoolbar
4. Dock the toolbar.
Set where the toolbar will be docked
Ctoolbar::enabledocking
Where the frame window allows docking
CFrameWnd::EnableDocking
Where the toolbar can be docked
CframeWnd::D Ocktoolbar
5. Toolbars for meals and hide
Cframewnd::showcontrolbar
void Cframewnd::showcontrolbar (ccontrolbar* pBar, bool bShow, bool bdelay); Bdelay now has no effect.
Cwnd::iswindowvisible--Determine whether the window is a display state to judge any window


The style of the window toolbar

Cbrs_size_dynamic--You can change the shape of the toolbar
Cbrs_tooltips--Change hint style
Cbrs_gripper--CLAMP/handle
Tbstyle_flat--toolbar button smoothing style
Tbstyle_transparent--toolbar button protrusion style

Status bar
Related classes
CStatusBarCtrl-Parent class CWnd, encapsulates various API functions for STATUSBARCTRL operations
CStatusBar--The parent class CControlBar, encapsulates the relationship between the status bar and the main frame window, including the creation of the status bar.

Use:
To create a status bar:
Cstatusbar::create/createex
Set the status bar indicator
CStatusBar::SetIndicators
Set the width and style of the indicator
Cstatusbar::setpaneinfo
Set the contents of the indicator

Cstatusbar::setpanetext

void EnableDocking (DWORD dwstyle); Specifies whether the control bar supports docking and the sides of its parent window to which the control bar can be dock Ed, if supported. Can is one or more of the following flags:cbrs_align_top allows docking at the TOP of the client area. Cbrs_align_bottom allows docking at the BOTTOM of the client area. Cbrs_align_left allows docking on the left side of the client area. Cbrs_align_right allows docking on the right side of the client area. Cbrs_align_any allows docking on any side of the client area. Cbrs_float_multi allows multiple control bars to being floated in a single mini-frame window. If Zero, that's, indicating no flags, the control bar does not the dock. void DockControlBar (CControlBar * PBar, UINT ndockbarid = 0, Lpcrect lpRect = NULL); Parameterspbarpoints to the control bar to being docked.ndockbariddetermines which sides of the frame window to consider for Docking. It can be 0, or one or more of the Following:afx_idw_dockbar_top Dock to the TOP side of the frame window. Afx_idw_dockbar_bottom Dock to the BOTTOM side of the frame window. Afx_idw_dockbar_left Dock to the left side of the frame window. Afx_idw_dockbar_right Dock to the right side of the frame window. If 0, the control bar can be docked to any side-enabled for docking in the destination frame window.lprectdetermines, in S Creen coordinates, where the control bar is docked in the nonclient area of the destination frame window. Cframewnd::showcontrolbarvoid Showcontrolbar (ccontrolbar* pBar, bool bShow, bool bdelay); Parameterspbarpointer to the control bar to being shown or hidden.bshowif TRUE, specifies that the control bar was to be shown . If FALSE, specifies that the control bar was to be hidden.bdelayif TRUE, delay showing the control bar.
