I wrote a program, can change the font color by color button

//I'm in pDC OnCtlColor function - & gt; SetTextColor (m_color1); Implementation of font changes color
GetDlgItem (CMFCColorButton m_color1=(*) (IDC_MFCCOLORBUTTON2)) - & gt; GetColor ();

Use color button control color, font color of the interface will not refresh; Controls can be dragged in my program, after I drag controls, font color will change

So I want to use a timer to refresh interface

O bosses give directions

Red mark of several variables is what kind of?

CodePudding user response:

Some people have done something like that before

CodePudding user response:

Can be used to Invalidate trigger redraws

 if (GetDlgItem (IDC_MFCCOLORBUTTON2)) 
{
GetDlgItem (IDC_MFCCOLORBUTTON2) - & gt; Invalidate (). 
} 

CodePudding user response:

From the code to guess int TMP; Cstrings m_value m_value2;

CodePudding user response:

If (GetDlgItem (IDC_MFCCOLORBUTTON2))
{
GetDlgItem (IDC_MFCCOLORBUTTON2) - & gt; Invalidate ().
}

How to use it? In the OnPaint, or on the OnCtlColor, or used in other functions?

You said Invalidate re-paint is how to get the

Use color button control color,
control. Invalidate ();

CodePudding user response:

I just added a button directly, and then click the function inside the
Invalidate ().
