Realization of the self-painted menu
Wenyi translation
A CCustomMmenu is provided here, which is a subclass of CMenu and has self-painting capabilities. It can provide you with the following features:
Set the font color. Set high brightness colors. Set the style of high brightness. Set the icon that is selected and in a menu in a normal state. Set the display icon size.
The structure Menudata is defined in the CCustomU, you must fill this structure according to your needs, and provide the pointer to the structure (call Appendmenu, InsertMenu) when adding menus. Below is an example:
1. Define the instance of CCUSTomMenu, and Menudata structural variables.
CCustomMMmenu M_CCUSTommenu;
Menudata Menudata [8]; // AS Many Menu Items Are Present, You Should Be Able To Use
// new and do the same
2. Call the createMenu () Set the relevant parameters.
m_customMenu.createMenu ();
M_CustomMenu.seticonsize (25, 25); // this is to set the size of the icon.
// this sales be used only overce for any menu
// in Order To Resize It, Destroy and Create The Menu Again with Different Size.
m_customMenu.SethighlightStyle (Normal); // or textonly, if you want the
// Background Color to Remain The Same
// and the text color to change to the highlight color.
// The Following SetXxxcolor Sets The Menu Colors. If you dont want to change any, dont call these member functions.
m_customMenu.SetTextColor (RGB (255, 0, 0));
M_CustomMenu.SetBackColor (RGB (255, 255, 255);
m_customMenu.SethighlightColor (RGB (0,0,255));
3, set the menuData variable and increase the menu item.
LSTRCPY (Menudata [0] .MenutexT, "Text1");
MenuData [0] .Menuiconnormal = IDI_ICON1;
m_customMenu.Appendmenu (MF_OWNERDRAW, 3, (LPCTSTR) MENUDATA);
3, overmeasure the onMeasureItem (...) function in your window.
Void CMYVIEW :: OnMeasureItem (int Nidctl, LpMeasureItemstruct LpMeasureItemstructure)
{
IF (LpMeasureItemstruct-> CTLTYPE == ODT_MENU &&
IsMenu ((HMENU) LPMeasureItemStruct-> ItemID &&
(lpMeasureItemstruct-> itemid == (uint) m_hmenusub))
{
m_customMenu.MeasureItem (lpMeasureItemstruct);
}
Else
// Let MFC's self-drawing handle it
CView :: OnMeasureItem (NidctL, LpMeasureItemstructure);
The following functions will help you set the menu properties.
Void SetTextColor (ColorRef);
Void SetBackColor (ColorRef);
Void SthighlightColor (ColorRef);
Void seticonsize (int, int);
Void SthighlightStyle (HighlightStyle); // HighlightStyle: Enum {Normal, Textonly}
Void STHighlightTextColor (ColorRef);
