1. 使用鼠标滚轮 Delphi的 ScrollBox 组件默认不支持鼠标滚轮滚动,但可以通过编程实现这一功能。你需要处理 ScrollBox 的OnMouseWheel 事件。 以下是一个示例代码,展示了如何为 ScrollBox 添加滚轮支持: pascal procedure TForm1.ScrollBox1MouseWheel(Sender: TObject; Shift: TShiftState; WheelDelta: Integer; MousePos...
在鼠标的MouseWheel事件里写入以下内容 if WheelDelta < 0 then SendMessage(scrollBox1.Handle, WM_VSCROLL, SB_LINEDOWN, 0) //向下滚 else SendMessage(scrollBox1.Handle, WM_VSCROLL, SB_LINEUP, 0); //向上滚 即可响应鼠标滚轮
delphi让ScrollBox响应鼠标的滚动消息 procedure ScrollBox1MouseWheelUp(Sender: TObject; Shift: TShiftState; MousePos: TPoint; var Handled: Boolean); procedure ScrollBox1MouseWheelDown(Sender: TObject; Shift: TShiftState; MousePos: TPoint; var Handled: Boolean); private procedure getmouse(var msg:...
Delphi7中ScrollBox控件是不响应鼠标滚轮事件的，让其响应鼠标滚轮方法如下： procedure TForm1.FormMouseWheel(Sender: TObject; Shift: TShiftState; WheelDelta: Integer; MousePos: TPoint; var Handled: Boolean);begin if WheelDelta < 0 then ScrollBox1.Perform(WM_VSCROLL,SB_LINEDOWN,...
