如何更改对话框中特定按钮的颜色 [英] How can I change a color for a specific button on my dialog

问题描述

我有一个名为RoundBtn.cpp的源文件及其头文件RoundBtn.h



这两个文件负责着色我的Dialog上的entier按钮。我需要做的是给我的一个按钮一个特殊的颜色。下面给出了一些着色所有按钮的代码。

I have a source file called RoundBtn.cpp with its header file RoundBtn.h

these two files are responsable for coloring the entier buttons on my Dialog. What i need to do is to give one of my button a special color. Some of the code for coloring all buttons is given below.

void RoundBtn::DrawItem(LPDRAWITEMSTRUCT lp)
{
	CRect rc = lp->rcItem;
	CDC dc;
	dc.Attach(lp->hDC);
	dc.SetBkMode(TRANSPARENT);
	CBrush br;
	br.CreateStockObject(NULL_BRUSH);
	dc.SelectObject(&br);
	if (is_pressed) // when the button is pressed
	{
		CPen pen(PS_SOLID, 2, RGB(0,0,0));
		dc.SelectObject(&pen);
		CBrush *pBrush=new CBrush(RGB(220,100,220));
		dc.SelectObject(pBrush);
		dc.RoundRect(0, 0, rc.Width(), rc.Height(), rc.Height()/1, rc.Height()/1);  // Round the Buttons 
		dc.SetTextColor(RGB(0, 0, 0));

什么我试过了：



我可以在主文件上更改什么，或者我可以在主文件上调用什么来为按钮着色。按钮ID Adress是

What I have tried:

What sould i change on my main file or what sould i call on my main file to color the button. the button ID Adress is

IDM_APPLY

，其功能是

and its function is

void CVCDlg::Apply1()
{

OnButtonApplyrange(); 

}

推荐答案

用于构造* pBrush的颜色是需要调整的颜色。您可以将颜色变量（COLORREF）设置为RoundBtn类的成员，并在类构造函数中将其设置为220,100,220。然后添加一个方法来设置颜色成员，如果你愿意，你可以让每个按钮都是不同的颜色。

The color used to construct the *pBrush is the one that needs to be adjusted. You could make a color variable (COLORREF) a member of the RoundBtn class and set it to 220,100,220 in the class constructor. Then add a method to set the color member and you can have each button be a different color if you wanted to.
