基于上一篇, 继续向basic.xml中添加下面的代码。 xml完整源码在文末。
<HBox>
<VBox>
<!-- Progress -->
<HBox margin="0,10" height="32">
<Progress class="progress_blue" name="progress" value="0" margin="10"/>
</HBox>
<!-- Slider -->
<HBox margin="0,0,0,10" height="32">
<Slider class="slider_green" name="slider" value="0" margin="10"/>
</HBox>
</VBox>
<VBox width="120">
<CircleProgress name="circle_progress" circular="true" height="80" width="80"
circlewidth="10" bgcolor="gray" fgcolor="green" value="0" clockwise="true" min="1" max="100" margin="10"
textpadding="10,32,10,10" normaltextcolor="darkcolor" indicator="logo_18x18.png"/>
</VBox>
</HBox>
</HBox>
这里，创建了slider,progress和circleprogress控件，如上图样式显示。
// progressbar
ui::Progress* pprogress_;
// slider
ui::Slider* pslider_;
// 圆形进度条
ui::CircleProgress* pcircle_progress_;
类中继续添加下面的代码，用于监听滑块的值发生变化
// 用于处理slider值变化时设置进度条和环形进度条的值
bool OnSliderValueChanged(ui::EventArgs* msg);
void BasicForm::InitWindow()
{
......
// 9.关联progress控件
//----------------------------------------------------------------------------------------
pprogress_ = dynamic_cast<ui::Progress*>(FindControl(L"progress"));
// 10.关联slider控件
//----------------------------------------------------------------------------------------
pslider_ = dynamic_cast<ui::Slider*>(FindControl(L"slider"));
if (pslider_)
{
pslider_->AttachValueChange(nbase::Bind(&BasicForm::OnSliderValueChanged, this, std::placeholders::_1));
}
// 11. 关联环形进度条
//----------------------------------------------------------------------------------------
pcircle_progress_ = dynamic_cast<ui::CircleProgress*>(FindControl(L"circle_progress"));
if (pcircle_progress_)
{
pcircle_progress_->SetValue(0);
pcircle_progress_->SetText(L"0");
}
// 设置最大和最小值
//----------------------------------------------------------------------------------------
// 因为slider和circlieprogress控件都是继承的Progress
auto set_progress_border = [](ui::Progress* pcontrol)
{
if (pcontrol)
{
pcontrol->SetMinValue(min_val_0);
pcontrol->SetMaxValue(max_val_100);
}
};
set_progress_border(pprogress_);
set_progress_border(pslider_);
set_progress_border(pcircle_progress_);
}
OnSliderValueChanged函数源码如下：
bool BasicForm::OnSliderValueChanged(ui::EventArgs* msg)
{
if (pprogress_ && pslider_ && pcircle_progress_)
{
double cur_val = pslider_->GetValue();
// 设置进度条显示
pprogress_->SetValue(cur_val);
// 设置环形进度条
pcircle_progress_->SetValue(cur_val);
TCHAR szBuffer[32] = { 0 };
swprintf_s(szBuffer, _T("%.0f%%"), cur_val);
pcircle_progress_->SetText(szBuffer);
}
return false;
}
