c++ - 调整 wxDialogs 的大小，使所有文本都在对话框中

Question

我的 wxWidgets 程序应该可以在桌面 PC 和 Windows 平板电脑上运行。两者均使用 Windows 10 Pro 64 位版本。我怎样才能使大小不断变化的文本无论在对话框中显示在何处？

这就是我现在做的:

TrackDialog::TrackDialog(wxWindow* parent,wxWindowID id,const wxPoint& pos,
                         const wxSize& size)
{
    //(*Initialize(TrackDialog)
    wxBoxSizer* BoxSizer4;
    wxBoxSizer* BoxSizer5;
    wxBoxSizer* BoxSizer2;
    wxBoxSizer* BoxSizer1;
    wxBoxSizer* BoxSizer3;
    wxBoxSizer* pPanelSizer;

    Create(parent, wxID_ANY, wxEmptyString, wxDefaultPosition, wxDefaultSize, wxSTAY_ON_TOP|wxSUNKEN_BORDER, _T("wxID_ANY"));
    Panel1 = new wxPanel(this, ID_PANEL1, wxDefaultPosition, wxDefaultSize, wxTAB_TRAVERSAL, _T("ID_PANEL1"));
    pPanelSizer = new wxBoxSizer(wxVERTICAL);
    BoxSizer1 = new wxBoxSizer(wxHORIZONTAL);
    StaticSelectText = new wxStaticText(Panel1, ID_STATICTEXT1, _("Select a *.xml file."), wxDefaultPosition, wxDefaultSize, 0, _T("ID_STATICTEXT1"));
    BoxSizer1->Add(StaticSelectText, 1, wxALL|wxEXPAND|wxALIGN_CENTER_HORIZONTAL|wxALIGN_CENTER_VERTICAL, 5);
    pPanelSizer->Add(BoxSizer1, 0, wxALL|wxEXPAND|wxALIGN_CENTER_HORIZONTAL|wxALIGN_CENTER_VERTICAL, 5);
    BoxSizer2 = new wxBoxSizer(wxHORIZONTAL);
    XmlFilePickerCtrl = new wxFilePickerCtrl(Panel1, ID_FILEPICKERCTRL1, _T("./resources/"), wxEmptyString, _T("*.xml"), wxDefaultPosition, wxDefaultSize, wxFLP_FILE_MUST_EXIST|wxFLP_OPEN|wxFLP_USE_TEXTCTRL, wxDefaultValidator, _T("ID_FILEPICKERCTRL1"));
    BoxSizer2->Add(XmlFilePickerCtrl, 1, wxALL|wxALIGN_CENTER_HORIZONTAL|wxALIGN_CENTER_VERTICAL, 5);
    pPanelSizer->Add(BoxSizer2, 0, wxALL|wxEXPAND|wxALIGN_CENTER_HORIZONTAL|wxALIGN_CENTER_VERTICAL, 5);
    BoxSizer3 = new wxBoxSizer(wxHORIZONTAL);
    StaticNumberText = new wxStaticText(Panel1, ID_STATICTEXT2, _("Tracknumber \n"), wxDefaultPosition, wxDefaultSize, 0, _T("ID_STATICTEXT2"));
    StaticNumberText->Disable();
    wxFont StaticNumberTextFont(10,wxSWISS,wxFONTSTYLE_NORMAL,wxNORMAL,false,_T("Arial"),wxFONTENCODING_DEFAULT);
    StaticNumberText->SetFont(StaticNumberTextFont);
    BoxSizer3->Add(StaticNumberText, 1, wxALL|wxALIGN_CENTER_HORIZONTAL|wxALIGN_CENTER_VERTICAL, 5);
    pPanelSizer->Add(BoxSizer3, 0, wxALL|wxEXPAND|wxALIGN_CENTER_HORIZONTAL|wxALIGN_CENTER_VERTICAL, 5);
    BoxSizer4 = new wxBoxSizer(wxHORIZONTAL);
    ChoiceTrack = new wxChoice(Panel1, ID_CHOICE1, wxDefaultPosition, wxDefaultSize, 0, 0, 0, wxDefaultValidator, _T("ID_CHOICE1"));
    ChoiceTrack->Disable();
    BoxSizer4->Add(ChoiceTrack, 1, wxALL|wxALIGN_CENTER_HORIZONTAL|wxALIGN_CENTER_VERTICAL, 5);
    pPanelSizer->Add(BoxSizer4, 0, wxALL|wxEXPAND|wxALIGN_CENTER_HORIZONTAL|wxALIGN_CENTER_VERTICAL, 5);
    BoxSizer5 = new wxBoxSizer(wxHORIZONTAL);
    ButtonOk = new wxButton(Panel1, ID_BUTTON1, _("OK"), wxDefaultPosition, wxDefaultSize, 0, wxDefaultValidator, _T("ID_BUTTON1"));
    BoxSizer5->Add(ButtonOk, 1, wxALL|wxALIGN_CENTER_HORIZONTAL|wxALIGN_CENTER_VERTICAL, 5);
    pPanelSizer->Add(BoxSizer5, 0, wxALL|wxALIGN_CENTER_HORIZONTAL|wxALIGN_CENTER_VERTICAL, 5);
    Panel1->SetSizer(pPanelSizer);
    pPanelSizer->Fit(Panel1);
    pPanelSizer->SetSizeHints(Panel1);
    Center();

    Connect(ID_FILEPICKERCTRL1,wxEVT_COMMAND_FILEPICKER_CHANGED,(wxObjectEventFunction)&TrackDialog::OnXmlFilePickerCtrlFileChanged);
    Connect(ID_CHOICE1,wxEVT_COMMAND_CHOICE_SELECTED,(wxObjectEventFunction)&TrackDialog::OnChoiceTrackSelect1);
    Connect(ID_BUTTON1,wxEVT_COMMAND_BUTTON_CLICKED,(wxObjectEventFunction)&TrackDialog::OnButtonOkClick);
    //*)
    SetSize(DoGetBestClientSize());
    Fit();
}

文本从“轨道编号”更改为以下选项之一:

void TrackDialog::setOutputAndChoice()
{
    std::vector<wxString> storedTracks = m_xmlReader.getNamesOfTracks(m_path);
    int numberOfTracks  = storedTracks.size();
    StaticNumberText->Enable();
    wxString text;

    // Make sure there are tracks stored in the file.
    if(numberOfTracks > 0){
        text = "There are ";
        text += wxString::Format(wxT("%i"), numberOfTracks);
        text += " tracks stored in the selected file. Select one."
                "\nTrack 1 is the inner track.";
    }
    else{
        text = "Opening file failed. Please chose another"
                                   "file of the right format.";
    }
    StaticNumberText->SetLabel(text);
}

这就是它在台式机上的样子(在平板电脑上它看起来一样，感谢 SetSize(DoGetBestClientSize());)

我该怎么做才能显示所有文本？在我调用 SetSizerAndFit() 之前，我已经尝试在构造函数中设置它，但是如果我想关闭它，我的程序就会崩溃...

感谢您的帮助。

编辑:我在 sizer 中为 StaticNumberText 和其中的文本放置了一个面板，现在我能够显示所有文本，尽管现在 StaticText 下方有一些讨厌的空间:

必须有更好的方法来正确布局带有更改文本的对话框...

Sizers 需要一个 Action 才能进入游戏。用户更改主(或对话框)窗口的大小绝对是一个 Action 。

您还可以触发要求对话框窗口适合其子项的操作。在 TrackDialog::setOutputAndChoice()

结束时调用 Fit()
