在线等------关于listview改变指定行字体颜色的问题

//测试代码
//listview双击事件
void __fastcall TMainFrom::ListViewDblClick(TObject *Sender)
{
line = ListView->Selected->Index;
//ShowMessage(line);
}

//按钮1单击事件
void __fastcall TMainFrom::Button1Click(TObject *Sender)
{
int line;
ListView->Items->Item[line]->SubItems->Strings[1]= FormatDateTime("yyyy-MM-dd",DateTimePicker2->DateTime)+FormatDateTime(" HH:mm:ss",DateTimePicker3->DateTime);
ListView->Items->Item[line]->SubItems->Strings[2]= Edit3->Text;
ListView->Items->Item[line]->SubItems->Strings[4]= ComboBox2->Text;
}
现在请教点击Button1后如何将line对应这行字体颜色改为绿色！

PS：善用搜索，找到有关在ListViewAdvancedCustomDrawItem事件中实现，但通过测试只能实现鼠标点击某行后后改变当前行颜色。（如下）

void __fastcall TMainFrom::ListViewAdvancedCustomDrawItem(TCustomListView *Sender,
  TListItem *Item, TCustomDrawState State, TCustomDrawStage Stage,
  bool &DefaultDraw)
{
if(Item->Index==line) //line 行 (指定行)
{
ListView->Canvas->Brush->Color   =   clWhite   ;
ListView->Canvas->Font->Color    =   clRed;    //字体为  clBlue 颜色
}
else
suiListView->Canvas->Brush->Color   =   clWhite;
}
请大哥指点如何简单 实现点击Button1修改listview内容的同时完成此行为绿色

4 个解决方案

#1

int lineIndex;

__fastcall TForm1::TForm1(TComponent* Owner)
	: TForm(Owner)
{
	lineIndex = -1;
}

//---------------------------------------------------------------------------
void __fastcall TForm1::Button1Click(TObject *Sender)
{
	lineIndex = 1; // 修改第二行
	ListView->Items->Item[lineIndex]->SubItems->Strings[0] = "test";
	ListView->Items->Item[lineIndex]->SubItems->Strings[1] = Edit1->Text;
	ListView->Items->Item[lineIndex]->SubItems->Strings[2] = ComboBox1->Text;
}

// ---------------------------------------------------------------------------
void __fastcall TForm1::ListViewAdvancedCustomDrawItem(TCustomListView *Sender,
	TListItem *Item, TCustomDrawState State, TCustomDrawStage Stage, bool &DefaultDraw)
{
	if (Item->Index == lineIndex) // State.Contains(cdsSelected)
		Sender->Canvas->Font->Color = clBlue;
	else
		Sender->Canvas->Font->Color = clBlack;
}

#2

void __fastcall TForm4::Button2Click(TObject *Sender)
{
	line = 3;
	ListView1->Items->Item[line]->SubItems->Strings[1] = "111";
	ListView1->Items->Item[line]->SubItems->Strings[2] = "222";
	ListView1->Items->Item[line]->SubItems->Strings[4] = "4444";
        // 这3种好像都可以
	// ListView1->Refresh();
	// ListView1->Repaint();
	ListView1->Invalidate();
}

测试完成感谢各位大哥帮助，结贴！！！！！

int line,lineIndex;
//------------------------------------------------------------------------------------------------------------------------------	
__fastcall TMainFrom::TMainFrom(TComponent* Owner)
{
     lineIndex = -1;
 } 
//-----------------------------------------------------------------------------------------------------------------------------
lineIndex = line;
		ListView->Items->Item[lineIndex]->SubItems->Strings[1]= FormatDateTime("yyyy-MM-dd",DateTimePicker2->DateTime)+FormatDateTime(" HH:mm:ss",DateTimePicker3->DateTime);
		ListView->Items->Item[lineIndex]->SubItems->Strings[2]= Edit3->Text;
		ListView->Items->Item[lineIndex]->SubItems->Strings[4]= ComboBox2->Text;
		ListView->Refresh();//引用ksrsoft 代码，否则会出现Strings[1]    Strings[2]    Strings[4]变色其他不变的情况

手动触发重绘，建议使用 Invalidate 方法。
