Introduction

I've wanted to post an item for some time, so when I started working on this component, I decided it was going to be it. The image editing software "Paint Shop Pro" from Jasc software utilizes a unique combination of an edit, spin, and trackbar functionality. I decided to try to derive my own version of this and this is the result. Check the upper left are on the screenshot. I used VS 2003 but I see no reason why it can't be compiled and used with an earlier version. The only requirement is that IE5 is required because it requires 32 bit calls such as the GetPos32() API.

Using the code

Methods

• int GetValue() - Get the current value
• void SetValue(int nValue) - Sets the current value
• BOOL GetReadOnly() - Gets the readonly state of the edit field
• void SetReadOnly(BOOL fReadOnly) - Sets the readonly state of the edit field
• void GetRange(int& nMin,int& nMax) - Gets the allowed value range
• void SetRange(int nMin,int nMax) - Sets the allowed value range

Styles

• NES_SPIN - Includes the spin control
• NES_POPUP - Includes the button on the far right that pops up a floating trackbar
• NES_LIVEUPDATE - Updates the parent about the value while tracking. NEW
• NES_METER - Includes the small bar underneath the edit field.NEW

Messages

• NEM_GETPOS - Returns the current value as return value
• NEM_SETPOS - Sets the current value. Passed in LPARAM
• NEM_GETRANGE - Returns allowed range. WPARAM and LPARAM are treated as pointers to int's
• NEM_SETRANGE - Sets the allowed range. Min is in WPARAM and max in LPARAM
• NEM_GETREADONLY - Gets the readonly state of the edit field. NEW
• NEM_SETREADONLY - Sets the readonly state of the edit field. NEW

Notifications

• NEN_CHANGED - Sent to the owner window when the value changes

// Declare a CNumericEdit

CNumericEdit m_Edit;        
        
//

// Creating the control

//

CRect rcRect(10,10,142,40);
m_Edit.Create(WS_VISIBLE | WS_TABSTOP | NES_SPIN | NES_POPUP,rcRect,this,0);
m_Edit.SetValue(50);
m_Edit.SetRange(0,100);

Todo

• Make the popup trackbar size configurable
• XP support ??
• Bitmap in popup trackbar (just like Paint Shop Pro) ?

History

4/13/2004 - 1.0

• Initial version

4/20/2004 - 1.01

• Fixed bug where the edit would only accept hex digits. Also now allow negative sign "-" to be entered
• Added NES_METER style to make the small bar under the edit field optional
• Control will now reconfigure itself when changing style bits
• Fixed max value bug. The full range is now accesible with the popup
• Added NES_LIVEUPDATE style. This style allows the control to notify it's parent during value tracking. Without this style, the parent is updated only at the end of tracking
• Demo has been updated to show the new features
• Added DDX_NumericEdit() function for DDX support
• Now using the active window caption color for the bar colors
• Changed hardcoded custom messages to use windows registered messages so as not to cause any conflict with other custom messages

In the example the main dialog receives the NEN_CHANGED message when the value has changed and then the buddy edit control is updated with the new value. If I use this method of receiving NE_CHANGED msgs, how do I know which CNumericEdit was changed? Is the control ID passed in wParam or lParam?

Ed Sign In·View Thread·PermaLink Make it no activating YYuri 9:39 14 Sep '06   Thank you for the nice control! But change 2 things: 1. Remove WS_VISIBLE style from the CreateEx call. 2. Replace SetWindowPos(0,x,y,0,0,SWP_NOSIZE | SWP_NOZORDER) few lines below with SetWindowPos(&wndTop,x,y,0,0,SWP_NOACTIVATE | SWP_NOSIZE | SWP_SHOWWINDOW) ...and dialog caption will not flicker to no-activated state when popup appears. Sign In·View Thread·PermaLink A simple extension Steve Johnson (Sven) 14:36 13 Jun '05   Nice article and very useful. I have created a simple spinner derivation that could give the same results, while retaining much of the standard control operation. This approach preserves the "buddy" relationship between the spin control and the edit box, and as well uses the dialog fonts mentioned by another reader. It also does not require a CWnd derived class to parent the edit and spin control. Instead of having a separate button (CMyButton), this uses a right click on the up/down control to show the slider popup. I personally like more with less, so this works for me. This also doesn't paint the bar below the edit control as yours does, but I would suggest overriding OnPaint() for your CMyEdit control and after calling CEdit::Paint(), simply draw a bar on the bottom two pixels of the edit control. You can test this approach by using CMySpinEditCtrl instead of the CSpinEditCtrl for m_spnMin, m_spnMax, etc, in your demo program. // Put this in NumericEdit.h //////////////////////////////// class CMySpinButtonCtrl : public CSpinButtonCtrl { DECLARE_DYNAMIC(CMySpinButtonCtrl) protected: DECLARE_MESSAGE_MAP() public: afx_msg void OnRButtonDown(UINT nFlags, CPoint point); afx_msg void OnLButtonUp(UINT nFlags, CPoint point); afx_msg LRESULT OnSetPos(WPARAM /*wParam*/,LPARAM nNewValue); }; // Put this in NumericEdit.cpp ///////////////////////////// IMPLEMENT_DYNAMIC(CMySpinButtonCtrl, CSpinButtonCtrl) BEGIN_MESSAGE_MAP(CMySpinButtonCtrl, CSpinButtonCtrl) ON_WM_RBUTTONDOWN() ON_WM_LBUTTONUP() ON_REGISTERED_MESSAGE(NEM_SETPOS,OnSetPos) END_MESSAGE_MAP() void CMySpinButtonCtrl::OnRButtonDown(UINT nFlags, CPoint point) { CSpinButtonCtrl::OnRButtonDown(nFlags,point); CMyTrackPopup* pTrackPopup = new CMyTrackPopup(); CRect rcRect; GetWindowRect(rcRect); // Get button location to determine popup location int min, max, pos; GetRange32( min, max ); pos = GetPos32(); pTrackPopup->Create( rcRect.left + point.x,rcRect.bottom + 4, min, max, pos, this); } void CMySpinButtonCtrl::OnLButtonUp(UINT nFlags, CPoint point) { CSpinButtonCtrl::OnLButtonUp(nFlags,point); CEdit* editPtr = (CEdit*)this->GetBuddy(); editPtr->SetSel( -1, 0 ); // Turn off the edit selection } afx_msg LRESULT CMySpinButtonCtrl::OnSetPos(WPARAM /*wParam*/,LPARAM nNewValue) { SetPos32((int)nNewValue); return 0; } Cheers, Steve Sign In·View Thread·PermaLink Re: A simple extension niry 7:19 18 Aug '05   A newbie cannot know right click on spin button, so it's not a good design. The original one is complex but intuitionistic. Sign In·View Thread·PermaLink Re: A simple extension Steve Johnson (Sven) 7:28 18 Aug '05   Not all applications are for newbies and intuitive ( especially JASC Paint Shop Pro! ) I am still learning about all the hidden features in Visual Studio for example. Early on I learned to right click on controls to see what happens - and I'm always surprized to find a new easter egg. Good Design for a user interface is very subjective and ultimately up to the end user to decide. Cheers, Steve Sign In·View Thread·PermaLink CMyEdit viva dotnet 8:42 24 Jun '04   I changed the color of the edit box (say RED in CtlColor ) and added a checkbox to enable / disable display of edit box. The edit box doesn't get repainted it says red until I move the NumericEdit dlg window around then it gets repainted ? any idea ? what do I need to do to enfoce repaint thanks Sign In·View Thread·PermaLink Does not work for VC6. WREY 12:57 25 Apr '04   VC6 MFC and VC7 MFC are two different set of classes, and your sample bears testament to that. Having IE6 makes no difference. SetPos32 and GetPos32 do. William Fortes in fide et opere! Sign In·View Thread·PermaLink Nice, but two mods needed Robin Hilliard 0:48 23 Apr '04   hi - This is a very useful control, but there are two minor problems with it: 1. It uses the system default font, rather than the default dialog font, hence it looks 'out of place' 2. The control is dynamically created on the dialog, rather than subclassed (or even overlaid) so the position and size are both hardcoded, which is a Bad Thing. Neither of these are difficult to fix and I'd do them myself and submit changes, if I'd more time. Sign In·View Thread·PermaLink Re: Nice, but two mods needed viva dotnet 8:44 24 Jun '04   Did you try to change the editbox bkg color to some other color and try to enable/disable the display of editbox? the repainting doesn't happen...would you know why?
