wxFrame starts with extremely small size.

Post by apoorv569 » Tue May 18, 2021 8:46 am

In my project I had 2 classes, MainFrame and Browser. The MainFrame was inheriting from wxFrame, and just defined the frame and nothing else just a couple of lines, that set the title, position, size and a object to Browser class which was inheriting from wxPanel and had all GUI widgets defined in it. But recently I merged the 2 into one class called MainFrame. After adjusting a couple of things needed to fix the merge process, I got it working, but I noticed for some reason, when I launch the app it starts extremely small, I can resize it, and everything seems to work fine no crash or anything. What could cause this size issue, here is a screenshot of when I launch the application,

And here is the relevant code, where I set the set size for the frame,

Code: Select all

void MainFrame::LoadConfigFile()
{
    int height = 600, width = 800;

    Settings settings(m_ConfigFilepath, m_DatabaseFilepath);
    Serializer serialize(m_ConfigFilepath);

    wxString font_face = serialize.DeserializeDisplaySettings().font_face;
    int font_size = serialize.DeserializeDisplaySettings().font_size;

    serialize.DeserializeBrowserControls("autoplay", bAutoplay);
    serialize.DeserializeBrowserControls("loop", bLoop);
    serialize.DeserializeBrowserControls("muted", bMuted);

    height = serialize.DeserializeWinSize("Height", height);
    width = serialize.DeserializeWinSize("Width", width);

    settings.GetFontType().SetFaceName(font_face);
    settings.GetFontType().SetPointSize(font_size);

    this->SetFont(settings.GetFontType());
    this->SetSize(width, height);
    this->CenterOnScreen(wxBOTH);
    this->SetIcon(wxIcon("../assets/icons/icon-hive_24x24.png", wxICON_DEFAULT_TYPE, -1, -1));
}
I call this method in the first line of the constructor,

Code: Select all

MainFrame::MainFrame()
    : wxFrame(NULL, wxID_ANY, "SampleHive", wxDefaultPosition),
      m_ConfigFilepath("config.yaml"), m_DatabaseFilepath("sample.hive")
{
    LoadConfigFile();
.
.
.
}

Sorry, but the obvious question needs to be asked (aside GTK version you use): Are you sure the window size retrieved from config is what you expect it to be?

I do not use Linux but AFAIK, the window creation is deferred there but I think wxWidgets works around it. Still, I would try loading the config using CallAfter() instead of directly from the ctor. But it does seem silly.

Yes, it does retrieve the correct size from the config file, I had print statements before and after fetching the values from config file, and it does indeed retrieve them.

I see, It was working before though, when I had separate class for wxFrame and the wxPanel. I'll try CallAfter() and see if that helps.

Do you have a SetSizerAndFit() call or something similar later in the code?
Use the source, Luke!

I figured out the problem when you said this. I had this in the code,

Code: Select all

    this->SetSizer(m_MainSizer);
    m_MainSizer->Fit(this);
    m_MainSizer->SetSizeHints(this);
    m_MainSizer->Layout();
I changed it to,

Code: Select all

    this->SetSizer(m_MainSizer);
    this->Layout();
    this->Center(wxBOTH);
This fixed the problem. I think I forgot to change this as "this" was wxPanel previously.
