Slider Control)

All controls are created on the same path;

Step 1: Create a csliderctrl Class Object in. h;

Csliderctrl m_ctrlslider;

Step 2: Initialize the control using the void cmydlg: dodataexchange (cdataexchange * PDX) function in. cpp; // initialize the control

Void cmydlg: dodataexchange (cdataexchange * PDX)

{

// This function is used to exchange data between controls and class members.

Cdialog: dodataexchange (PDX );

// Special slider

Ddx_control (PDX, idc_slider1, m_ctrlslider );

}

Step 3: Set initialization in the bool cmydlg: oninitdialog () function; // set Initialization

Bool cmydlg: oninitdialog ()

{

Cdialog: oninitdialog ();

.........

M_ctrlslider.setrange (0,100); // you can specify the maximum and minimum values of the slider position.

M_ctrlslider.setpos (30); // you can specify the default position of the slider.

}

Step 3: Add event processing functions;

After initialization, add an event processing function to obtain the corresponding data when adjusting the slider position;

Add function declaration in 1.h

Afx_msg void onnmcustomdrawslider1 (nmhdr * pnmhdr, lresult * presult );

2. Add a message:

Begin_message_map (cmydlg, cdialog)

.........

On_notify (nm_customdraw, idc_slider1, onnmcustomdrawslider1)

.........

3. function definition; // This function is called through (2) when the slider is adjusted;

// Main Window Slider

Void cmydlg: onnmcustomdrawslider1 (nmhdr * pnmhdr, lresult * presult)

{

Int NPOs = m_ctrlslider.getpos (); // obtain the current position of the slider

// Make another edit box to display the adjusted data;

Cstring STR = _ T ("");

Str. Format (_ T ("% d %"), NPOs );

Setdlgitemtext (idc_edit13, STR );

}
