wxWidgets behaviour different on 2 computers? Topic is solved

[albinoblacksheep]

Hello,

I have written a small prototype in C++ and compiled it on Windows 10 using MinGW32.

While the program works as intended on my PC the program behaves different on a second machine (Windows 10 as well):

On my PC the textCtrl are textCtrl while the textCtrl on the other machine appears as sliders:

Please look at the images. What could cause that a compiled program displays on the one machine the textCtrl correctly while on the second machine sliders instead of txtCtrl?

Those are not sliders, but scrollbars.
How do you create a wxTextCtrl? Are you using wxTE_MULTILINE or wxHSCROLL or wxTE_DONTWRAP ?

Thank you for looking into this.

Indeed wxTE_DONTWRAP was set (the others not). So I build a new version for testing and will report if this fixes it. Interesting is that I have another ListBox (different name and on a different Tab) where the problem does not occur.

For my better understanding: If I select wxTE_DONTWRAP why this could cause having a scrollbar? Multiline and HSCROLL sounds logic that this might result in a scrollbar, but DONTWRAP? The textCtrl is long enough to ensure that the string fits into.

This is how the textCtrls are created:

Code: Select all

    jg_id = new wxTextCtrl(Panel9, ID_TEXTCTRL17, wxEmptyString, wxPoint(136,16), wxSize(152,27), wxTE_DONTWRAP, wxDefaultValidator, _T("ID_TEXTCTRL17"));
    jg_status = new wxTextCtrl(Panel9, ID_TEXTCTRL18, wxEmptyString, wxPoint(136,64), wxSize(152,27), wxTE_READONLY, wxDefaultValidator, _T("ID_TEXTCTRL18"));
    jg_designation = new wxTextCtrl(Panel9, ID_TEXTCTRL19, wxEmptyString, wxPoint(136,112), wxSize(152,27), wxTE_READONLY, wxDefaultValidator, _T("ID_TEXTCTRL19"));
    jg_latitude = new wxTextCtrl(Panel9, ID_TEXTCTRL20, wxEmptyString, wxPoint(136,160), wxSize(152,27), wxTE_READONLY, wxDefaultValidator, _T("ID_TEXTCTRL20"));
    jg_longitude = new wxTextCtrl(Panel9, ID_TEXTCTRL21, wxEmptyString, wxPoint(136,208), wxSize(152,27), wxTE_READONLY, wxDefaultValidator, _T("ID_TEXTCTRL21"));
    jg_distance = new wxTextCtrl(Panel9, ID_TEXTCTRL22, wxEmptyString, wxPoint(136,256), wxSize(152,27), wxTE_READONLY, wxDefaultValidator, _T("ID_TEXTCTRL22"));

and this is how they get filled

Code: Select all

// Select infos from DB and put them into ListBox
        sql << "SELECT name FROM info order by NAME;";
    ListBox1->InsertItems(getListBoxContent(sql), 0);
        sql.clear();
        sql.str("");
        sql << "SELECT designation FROM entry UNION ALL SELECT designation FROM exit ORDER BY designation;";
    ListBox2->InsertItems(getListBoxContent(sql), 0);
        sql.clear();
        sql.str("");

If I select wxTE_DONTWRAP why this could cause having a scrollbar?

I believe wxTextCtrl docs answer that question.
However, you do not need that style for a single line text ctrl.

How do you know the text control is long enough? You cannot see the text because of the scrollbar. Beside, that flag forces the showing of the scrollbar, see the docs.


Off topic: you should not use explicit sizes and positions, but use sizer-based layout. You will find very good docs and tutorials about it.

This is probably the main problem. I guess the other computer you tested on had a different font scaling and therefore the hard-coded sizes were too small and you ended up with scrollbars.
