Question

我在Windows上使用wxProgressDialog。每当我更改对话框中的文本时，对话框会重新调整大小以适应文本，这会导致对话框经常重新调整大小，看起来很糟糕。

我尝试过SetMinSize和SetSizeHints，但这些似乎没有效果。 SetSize似乎也不起作用。

（有关信息，对话框显示文件传输的进度。当传输每个文件时，将显示其完整路径。这些变化很大，导致不断重新调整大小。）

我的代码基于示例中的代码：

static const int max = 100;

wxProgressDialog dialog("Progress dialog example",
                        // "Reserve" enough space for the multiline
                        // messages below, we'll change it anyhow
                        // immediately in the loop below
                        wxString(' ', 100) + "\n\n\n\n",
                        max,    // range
                        this,   // parent
                        wxPD_CAN_ABORT |
                        wxPD_CAN_SKIP |
                        wxPD_APP_MODAL |
                        //wxPD_AUTO_HIDE | // -- try this as well
                        wxPD_ELAPSED_TIME |
                        wxPD_ESTIMATED_TIME |
                        wxPD_REMAINING_TIME |
                        wxPD_SMOOTH // - makes indeterminate mode bar on WinXP very small
                        );

bool cont = true;
for ( int i = 0; i <= max; i++ )
{
    wxString msg;

    // test both modes of wxProgressDialog behaviour: start in
    // indeterminate mode but switch to the determinate one later
    const bool determinate = i > max/2;

    if ( i == max )
    {
        msg = "That's all, folks!\n"
              "\n"
              "Nothing to see here any more.";
    }
    else if ( !determinate )
    {
        msg = "Testing indeterminate mode\n"
              "\n"
              "This mode allows you to show to the user\n"
              "that something is going on even if you don't know\n"
              "when exactly will you finish.";
    }
    else if ( determinate )
    {
        msg = "Now in standard determinate mode\n"
              "\n"
              "This is the standard usage mode in which you\n"
              "update the dialog after performing each new step of work.\n"
              "It requires knowing the total number of steps in advance.";
    }

    // will be set to true if "Skip" button was pressed
    bool skip = false;
    if ( determinate )
    {
        cont = dialog.Update(i, msg, &skip);
    }
    else
    {
        cont = dialog.Pulse(msg, &skip);
    }

    // each skip will move progress about quarter forward
    if ( skip )
    {
        i += max/4;

        if ( i >= 100 )
            i = 99;
    }

    if ( !cont )
    {
        if ( wxMessageBox(wxT("Do you really want to cancel?"),
                          wxT("Progress dialog question"),  // caption
                          wxYES_NO | wxICON_QUESTION) == wxYES )
            break;

        cont = true;
        dialog.Resume();
    }

    wxMilliSleep(200);
}

if ( !cont )
{
    wxLogStatus(wxT("Progress dialog aborted!"));
}
else
{
    wxLogStatus(wxT("Countdown from %d finished"), max);
}

}

Answer 1

选择文件路径显示的大小。如果路径较短，请添加空格，如果更长时间用椭圆替换（...）

wxControl :: Ellipsize对此有用（http://docs.wxwidgets.org/3.1/classwx_control.html#a0bb834cae2a8986aceddb89f84ef4ed1）

Answer 2

如果你想要一个固定的大小，你需要使用wxGenericProgressDialog，似乎没有任何方法可以阻止默认在支持它的系统（Vista和更高版本）下使用的本机对话框，使其大小适应其内容。

如何阻止wxProgressDialog重新调整大小？
