extern "system" -- Usually the same as extern "C", except on Win32, in which case it's "stdcall", or what you should use to link to the Windows API itself
参考:
https://doc.rust-lang.org/reference/items/external-blocks.html#abi
这样的代码会报错
fn OnMouseDown(&self, sender: usize, button: TMouseButton, shift: TShiftState, x: i32, y: i32) {
println!("Button:{}, X:{} Y:{}", button == TMouseButton::mbLeft, x, y);
println!("OnMouseDown");
}
binary operation
==
cannot be applied to typerust_vcl::types::TMouseButton
是不是要加上#[derive(PartialEq, Debug)],方便输出和比较。
ASLR
,而liblcl没有支持ASLR
,造成使用上有问题,在linker参数中加入/DYNAMICBASE:NO
即可解决。pub type TNotifyEvent = fn(usize);
使用这样的定义之后就不能用捕获chk
,类似:
let chk = TCheckBox::new(&self.form);
...
action.SetOnUpdate(|sender: usize|{
let action: TAction = TAction::As(sender);
action.SetEnabled(chk.Checked());
});
会出现:
expected fn pointer, found closure错误。
是否可以改成:
https://stackoverflow.com/questions/57937436/how-to-alias-an-impl-trait
MessageDlg("中文", TMsgDlgType::mtInformation, TMsgDlgBtn::mbYes as u32, 0);
这样显示的按钮是OK,TMsgDlgBtn::mbNo
这个才是Yes,另外如果要多个按钮在WIN32里是类似TMsgDlgBtn::mbYes as u32 | TMsgDlgBtn::mbNo as u32
这样的方式么?
其次types.rs
里那些const常量应该加pub吧。
.SetOnLinkClick(sid, |cls: &TMainForm, sender: usize, link: *const c_char, linkType: TSysLinkType|{
println!("link label: {}, type: {:?}", to_RustString!(link), linkType);
});
是不是把to_RustString导出比较好,有些回调参数还是用到*const c_char
了。
