There are multiple dynamic button in the program, because will not achieve to add bitmap button one by one by one,

Therefore intend to create dynamic button, unified to dynamically add bitmap button, but this problem again,

Button text is covered, button bitmap, too, can't distinguish between each button,

So I want to ask how the bitmap button displays text

 MyButton * BTN=new MyButton (); 
BTN - & gt; Create (pStr, dwStyle, CRect (left, top, right, bottom), and this - & gt; GetParent (), IDC_D_BTN + index); 
BTN - & gt; LoadBitmaps (IDB_BITMAP_yp_c IDB_BITMAP_yp_d, IDB_BITMAP_yp_x IDB_BITMAP_yp_c); 

Or have any other good ideas can, bosses give advice or comments

CodePudding user response:

Or how can I not use a control variable, using the control ID add bitmap

CodePudding user response:

Can do pictures, text directly onto the reproduction, that's a lot of practical engineering;
You can also find a third-party text images, search a handful:

CodePudding user response:

You said that I think of, but, because I am a unified add bitmap, cause all button is the same picture, unable to distinguish

From a new class to handle CBitmapButton derived

 
//MyBitmapButton. H 
# pragma once 

The class CMyBitmapButton: public CBitmapButton 
{
DECLARE_DYNAMIC (CMyBitmapButton)

__super: : DrawItem (lpDIS); 

//get window need to display the string 
Cstrings szText;

//the CDC handle

//save DC

} 

CodePudding user response:

Not give you a class? Button you can add text, this kind of a lot of people have written,
Your "button to use the same image" the demand is not very reasonable, normal circumstances you will dynamically create button by different ID, different functions and different images,

CodePudding user response:

I also want to give each button to add different images, but they will not get
