修改右键弹出菜单的字体大小

Posted 2020-08-23 Energy

如果要修改右键弹出菜单的大小.  (另一个办法就是自己绘制了)

 

1. 先设置Screen->MenuFont->Size = 30; 你希望设置的字体大小
2. 然后将 PopMenu的OwnerDraw属性设置为true
3. 然后设置每个菜单项（TMenuItem）的OnMeasureItem 事件过程，设置菜单项的高度。

 

下面是实例代码

//---------------------------------------------------------------------------

#include <vcl.h>
#pragma hdrstop

#include "Unit1.h"
//---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma resource "*.dfm"
TForm1 *Form1;
//---------------------------------------------------------------------------
__fastcall TForm1::TForm1(TComponent* Owner)
    : TForm(Owner)
{
}
//---------------------------------------------------------------------------

void __fastcall TForm1::FormCreate(TObject *Sender)
{
    Screen->MenuFont->Size = 30;

}
//---------------------------------------------------------------------------
void __fastcall TForm1::N11MeasureItem(TObject *Sender, TCanvas *ACanvas,
      int &Width, int &Height)
{

    Height = ACanvas->TextHeight("高") + 10;

}
