wxDatePickerCtrl Topic is solved

[danlbom]

Hi, alls
I'm a newbie in wxWidgets and I have some question to ask.
How I can SetFormat in wxDatePickerCtrl ?
I mean I want this format "yy-mm-dd HH:MM:SS"
My point is how i can set time in wxDatePickerCtrl.
Could you tell me how i can do ?

thanks

Please read the documentation:

http://www.wxwidgets.org/manuals/2.8.0/ ... pickerctrl

SetValue() to set the value, SetFormat() to set the format. Two important remarks are made here:

The native version always uses the current system locale.

Sets the display format for the date in the control. See wxDateTime for the meaning of format strings.

thank you very much for reply
i have error

Code: Select all

m_oldestdate = new wxDatePickerCtrl( parent, wxID_ANY, wxDefaultDateTime, wxDefaultPosition, wxDefaultSize, wxDP_DEFAULT);
m_oldestdate->SetFormat(_T("%d/%m/%y HH:MM:SS"));

Error 1 error C2039: 'SetFormat' : is not a member of 'wxDatePickerCtrl' e:\clientwxdemo\syslogfilter.cpp 154

could you show me for some example, please ?

thanks

Like I said, read the documentation carefully. It says:

wxDatePickerCtrl::SetFormat

void SetFormat(const wxChar* format)

Please note that this function is only available in the generic version of this control. The native version always uses the current system locale.

In other words I think the SetFormat is not available for you if the native version is used.

Thank you for reply again

I'm try again with

Code: Select all

#include <wx/generic/datectrl.h>

wxDatePickerCtrlGeneric* m_newestdate;

m_newestdate = new wxDatePickerCtrlGeneric( parent, wxID_ANY, wxDefaultDateTime, wxDefaultPosition, wxDefaultSize, wxDP_DROPDOWN|wxDP_SHOWCENTURY );

m_newestdate->SetFormat(_T("%d/%m/y HH:MM:SS"));

and I have errors again

This will not work like this. Just including a class like this will not work because it is switched off in the wx build. What wxWidgets does is providing wrapper classes around the Windows API. If in setup.h delivered with wxWidgets the wxDateTimePicker is set to use the native one, the generic class is not compiled in the library thus with linking, it will not be found.

What you should do is find the setup.h that comes with your wx distrib, find the line that defines the wxDateTimePicker as native and set it to generic. Then recompile the libary and do not alter your code, just use wxDateTimePicker it will be typecasted to wxDateTimePickerGeneric.

On the other hand, it might not be possible to use the generic version on your platform. Be prepared for some work ahead in any way

Jorg,

Can you provide a few more details on how to do this? I'm trying to get the generic control on a Mac. I've edited setup.h to change the line

Code: Select all

#define wxUSE_DATEPICKCTRL 1

to

Code: Select all

#define wxUSE_DATEPICKCTRL_GENERIC 1

When I run make, I get

Code: Select all

../include/wx/chkconf.h:498:9: error: #error "wxUSE_DATEPICKCTRL must be defined."
../include/wx/chkconf.h:1456:5: warning: "wxUSE_DATEPICKCTRL" is not defined

Thanks for any help you can offer.

i have a similar problem. i built wxwidgets 2.9.4 with the default options in windows. in the file C:\wxWidgets-2.9.4_vc11\include\wx\msw\setup.h it sais

Code: Select all

#define wxUSE_DATEPICKCTRL  1   // wxDatePickerCtrl

but still i cannot use wxDatePickerCtrl (unresolved external symbol):

Code: Select all

error LNK2019: Verweis auf nicht aufgel÷stes externes Symbol ""__declspec(dllimport) public: __thiscall wxDatePickerCtrl::wxDatePickerCtrl(void)" (__imp_??0wxDatePickerCtrl@@QAE@XZ)" in Funktion ""public: void __thiscall ecwda::BuffersAndDevices::loadTestingDevices(void)" (?loadTestingDevices@BuffersAndDevices@ecwda@@QAEXXZ)".

what do i miss?

EDIT: SOLVED, i had to link to wxmsw29ud_adv.lib
