ID column doesn't appear until window is resized

Bug The string ID on the right does not appear if a .po file is just opened. It only appears if the window is resized to a smaller resolution and then resized to full screen.

Quoting another report by Antonio Rosella:

I'm using poedit 2.4.2 on an MXLInux 19.2 distribution ( an AntiX-Debian derivative, XFCE desktop https://mxlinux.org/ ). The package came from the distribution stable repository

Linux htpc 5.9.0-3mx-amd64 #1 SMP Debian 5.9.9-1~mx19+1 (2020-11-21) x86_64 GNU/Linux

Here attached you can find 3 snap that hopefully describe the issue. The first (poedit_1.jpg) is the opening window that pop up at the program startup: as you can notice, column "ID" it is not present at all, even if "View -> Show String ID" is selected

Now, if I enlarge the window on the right side, the ID colum show itself. (poedit_2.jpg) . You have to resize the full windows: if you try to resize only the "Translation suggestions" subwindow nothing happen

Again, reducing the window size, i can be noticed that the column "ID" start to resize, until it disappear completely (image poedit_3.jpg is a snap in the middle of the process...). It is at this point that the massages I sent you pop up on the console, arguing about "Negative content width -7 (allocation 5, extents 6x6) while allocating gadget (node button, owner GtkButton)"

It seems that on shrink of the window, the column "ID" start to reduce his size further than allowed

I can reproduce the issue with the following environment:

• Poedit version: 3.0.1
• wxGTK version: 3.1.6
• GTK+ version: 3.24.33
• Operating system: openSUSE Tumbleweed (20220414)

I think the issue comes from the fact the sizing of the ID column is not immediate - at least on wxGTK [^note].

So in PoeditListCtrl::UpdateColumns:

    if (m_displayIDs)
    {
        // determine best fitting width only once, then set it as fixed, because IDs are immutable
        m_colID->SetWidth(wxCOL_WIDTH_AUTOSIZE);
        m_colID->SetWidth(m_colID->GetWidth());
    }

the width returned by m_coldID->GetWidth() can actually be 0, hence the observed behaviour.

The CallAfter at the end of the method:

#ifdef __WXGTK__
    // wxGTK has delayed sizing computation, apparently
    CallAfter([=]{ SizeColumns(); });
#endif

has no effect since on the sizing of the ID column is made in UpdateColumns, not SizeColumns.

[^note]: This might be related to this node in wxDataViewColumn documentation:

> Note
>     In wxGTK, setting the width of the column doesn't happen immediately when [SetWidth()](https://docs.wxwidgets.org/trunk/classwx_settable_header_column.html#aac89bf5d893ccf57c3e50e3d1acbebea) is called, but only slightly later and [GetWidth()](https://docs.wxwidgets.org/trunk/classwx_header_column.html#a992a31984563a35b0222adf5a06b0a77) will return the old width (0 initially) until this happens. If the column widths are set before [wxDataViewCtrl](https://docs.wxwidgets.org/trunk/classwx_data_view_ctrl.html) is initially shown, they will only be effectively set when it becomes visible.
