如何仅通过单击其中的按钮来销毁 wxWidgets Popup？

问题描述

我使用“wxPopupTransientwindow”创建了一个弹出窗口并添加了一些文本和一个按钮。现在我只想在单击此特定按钮时销毁此弹出窗口。现在，如果点击它外面的任何地方，Popup 将被破坏。 这是我迄今为止尝试过的。

SimpleTransientPopup::SimpleTransientPopup(wxWindow *parent,bool scrolled) : wxPopupTransientwindow(parent,wxFRAME_SHAPED)
{

    m_bGotItClick = false;
    m_panel = new wxScrolledWindow(this,-1,wxDefaultPosition,wxDefaultSize);
    m_panel->SetBackgroundColour(*wxYELLOW);

    wxStaticText *text = new wxStaticText( m_panel,wxID_ANY,"This panel will guide you stepwise through the workflow\n");

    wxPanel *pBottomPanel = new wxPanel(m_panel,-1);
    m_button = new wxButton(pBottomPanel,Minimal_PopupButton,"Got it!",wxDefaultSize);
    m_link = new wxHyperlinkCtrl(pBottomPanel,Minimal_PopupLink,_("Hide these tips"),_(""),wxDefaultSize,wxHL_ALIGN_LEFT);
    m_link->SetFont(wxFont(10,wxFONTFAMILY_DEFAULT,wxFONTSTYLE_ITALIC,wxFONTWEIGHT_norMAL,true));
    m_link->SetnormalColour(*wxLIGHT_GREY);
    m_link->SetForegroundColour(*wxLIGHT_GREY);
    wxBoxSizer *topSizer = new wxBoxSizer( wxVERTICAL );
    wxBoxSizer *bottomSizer = new wxBoxSizer(wxHORIZONTAL);
    
    bottomSizer->Add(m_link,wxALL,20);
    bottomSizer->AddStretchSpacer();
    bottomSizer->Add(m_button,20);
    
    pBottomPanel->SetAutoLayout(true);
    pBottomPanel->SetSizer(bottomSizer);
    bottomSizer->SetSizeHints(pBottomPanel);
    bottomSizer->Fit(pBottomPanel);

    topSizer->Add(text,wxEXPAND | wxLEFT | wxRIGHT | wxTOP,20);
    topSizer->Add(pBottomPanel,wxEXPAND);
    
    m_panel->SetSizer( topSizer );
    // Use the fitting size for the panel if we don't need scrollbars.
    topSizer->Fit(m_panel);

    SetClientSize(m_panel->GetSize());
    wxTipKind tipKind = wxTipKind_Auto;
    const int offsetY = SetTipShapeAndSize(tipKind,GetBestSize());
    if (offsetY > 0)
    {
        // Offset our contents by the tip height to make it appear in the
        // main rectangle.
        topSizer->Prependspacer(offsetY);
    }
    m_panel->Fit();
}

我在单击按钮时调用此 Ondismiss 函数。

void SimpleTransientPopup::Ondismiss()
{
    if (m_bGotItClick) {
        wxLogMessage("%p SimpleTransientPopup::Ondismiss",this);
        wxPopupTransientwindow::Ondismiss();
        m_bGotItClick = false;
    }
}

PS：我是 wxWidgets 的新手

解决方法

通过覆盖“wxPopupTransientWindow::Dismiss()”，我可以在单击按钮时关闭弹出窗口。

void SimpleTransientPopup::Dismiss()
{
    if (m_bGotItClick) {
        wxLogMessage("%p SimpleTransientPopup::Dismiss",this);
        wxPopupTransientWindow::Dismiss();
        m_bGotItClick = false;
    }
}
