Page Setup Dialog settings not kept

[ercolesptr]

I have this code in my program and although it shows up the page setup dialog correctly, the settings inputed are not being kept and if I reopen the page setup again I find all settings gone back to default. Furthermore the settings inputed here are not used for the print job. Any Idea what I need to do?

Code: Select all

wxPrintData g_printData;
wxPrintDialogData g_printDialogData;

void Project1Frm::WxButton6Click(wxCommandEvent& event)
{
	wxPageSetupDialogData psdd(g_printData);
    WxPageSetupDialog1->ShowModal();
    psdd.EnablePrinter(true);
    psdd.EnablePaper(true);
    psdd.EnableOrientation(true);
    g_printData = wxPrintData(WxPageSetupDialog1->GetPageSetupDialogData().GetPrintData());
}

Hi,
Did you look at the printing sample?

What is your wx version and platform you test it on?

Thank you.

The platform is Windows 10, and wx version is 3.2.1. Here is the rest of the code:

Code: Select all

#include "Project1Frm.h"
#include <wx/msgdlg.h>
#include <wx/wx.h>
#include <wx/print.h>
#include <wx/printdlg.h>
#include <wx/cmndata.h>
#include <iostream>

wxPrintData g_printData;
wxPrintDialogData g_printDialogData;
static const int brush_size = 3;

class MyPrintout : public wxPrintout
{
    public: MyPrintout() : wxPrintout()
    {
        //
    }
    bool OnBeginDocument(int startPage, int endPage)
    {
        return wxPrintout::OnBeginDocument(startPage,endPage);
    }
    void OnBeginPrinting()
    {
        return wxPrintout::OnBeginPrinting();
    }
    void OnEndDocument()
    {
        return wxPrintout::OnEndDocument();
    }
    void GetPageInfo(int *minPage, int *maxPage, int *pageSelFrom, int *pageSelTo)

        *maxPage = 1;
        *pageSelFrom = 1;
        *pageSelTo = 1;
    }
    bool HasPage(int pageNum)
    {
        if (pageNum <= 2)
        {
            return true;
        }
        else
        {
            return false;
        }
    }
    void OnPreparePrinting()
    {
        return wxPrintout::OnPreparePrinting();
    }
    bool OnPrintPage(int pageNum)
    {
        //wxLocale locale(wxLANGUAGE_ENGLISH_MALTA);
        wxDC *ptr = GetDC();
        if (ptr == NULL || !ptr->IsOk())
        {
            return false;
        }
        wxDC& dc = *ptr;
        dc.Clear();
        dc.SetMapMode(wxMM_POINTS);
        dc.SetPen(wxPen(wxColor(0,0,0),brush_size));
        dc.SetBrush(wxBrush(*wxTRANSPARENT_BRUSH));
               		 
      dc.SetFont(wxFont(16,wxFONTFAMILY_SWISS,wxFONTSTYLE_NORMAL,wxFONTWEIGHT_BOLD,false,wxEmptyString,wxFONTENCODING_DEFAULT));
        dc.SetTextForeground(wxColor(0,0,0));
        dc.DrawText("This is a test",120,30);

        return true;
    }
    void OnEndPrinting()
    {
        return wxPrintout::OnEndPrinting();
    }
};

void Project1Frm::WxButton6Click(wxCommandEvent& event)
{
	wxPageSetupDialogData psdd(g_printData);
    WxPageSetupDialog1->ShowModal();
    psdd.EnablePrinter(true);
    psdd.EnablePaper(true);
    psdd.EnableOrientation(true);
    g_printData = wxPrintData(WxPageSetupDialog1->GetPageSetupDialogData().GetPrintData());

    {
        return;
    }
    wxPreviewFrame *frame = new wxPreviewFrame(preview, this, wxT("Print Preview"), wxPoint(100,100), wxSize(800,600));

	if (!printer.Print(this, &printout,true))
    {
        return;

    else

    }
}

I found that changing the line:

Code: Select all

wxPrinter printer;

to:

Code: Select all

wxPrinter printer(&g_printDialogData);

solved the problem for real printing, however for preview it is still not having any effect.

[ercolesptr]

I found the solution for preview as well. I needed to add this line in the preview function at the beginning:

Code: Select all

wxPrintDialogData g_printDialogData(g_printData);

[ercolesptr]

Just for completeness sake and also because I could not find any examples easily here is how the Page setup function should be:

Code: Select all

void Project1Frm::WxButton6Click(wxCommandEvent& event)
{
	wxPageSetupDialogData psdd;
	psdd=wxPageSetupDialogData(g_printData);
	psdd.EnablePrinter(true);
    psdd.EnablePaper(true);
    psdd.EnableMargins(true);
    psdd.EnableHelp(true);
    psdd.EnableOrientation(true);
	wxPageSetupDialog dialog( NULL, &psdd );
    dialog.ShowModal();
    g_printData = wxPrintData(dialog.GetPageSetupDialogData().GetPrintData());
}
