CHButton - CodeProject

Sample Image - CHButton.jpg

Introduction

The idea was simple, I needed to use simple hyperlink buttons in my application. I searched for them on the net and could not find any, so I decided to write down my own class of Hyperlink buttons. CHButton is a CButton derived class and its objects are simple buttons, with the user interface of a Hyperlink control. The only thing you'll have to do is to attach a cursor to it, which you can do using the function:

void SetCursor(BOOL HCURSOR m_Cursor);
Sets cursor of the Hyperlink button.

This class also has the following public methods:

void SetUnderline(UINT nUnderline);
Sets the chosen Underline state to the button. nUnderline can have the following values:

HS_ALWAYS - Displays the underline always.
HS_HOVER - Displays the underline when the mouse is over the button.
HS_NONE - Removes the underline if exists.

void SetHoverTextColor(COLORREF clrTextColor,BOOL bShowColor =TRUE);
Sets the Hyperlink button text color when the mouse is over the button.
void SetTextColor(COLORREF clrColor)
Sets the text color of the Hyperlink button.
void SetIcon(HICON Icon)
Sets the specified icon to the button.
void SetToolTip(LPCSTR strText, BOOL bActive = TRUE);
Sets the ToolTip text for the Hyperlink button.

How to Use it

Add "HButton.cpp" and "HButton.h" files to your project.
In your dialog's header file, write: #include "HButton.h".
Create a button on your dialog and in the Properties tab set the "owner draw" property.
Add a CButton m_btn variable to the just created button and in your dialog's header file rename it to CHButton m_btn.
Compile and enjoy it :)

I don't see the point...

I don't really understand the need for this class. It seems much better to me to just pass a string to a shell function, similar to this:

void CYourAppView::OnBrowser() 
{
         //pass this var instead of hard-coding
	CString szUrl = "http://www.someurl.com";
 
    // Use shell to invoke web browser on the URL.
    int iRes = (int) ShellExecute(NULL, NULL, (LPCTSTR)szUrl, NULL, NULL, 0);
 
    if (iRes <= 32)
    	//browser launch failed
    else
	//browser launch successful
}

This has the added advantage that you can not only link from buttons, but menu items, list items, or any object that can handle a mouse-click event.

If you want the blue text, etc, on your button, just subclass the button and then have your message handler pass the string var to the shell function.

In business, if two people always agree, one of them is unnecessary.

Exactly.. I don't understand the point of the class.

CHButton objects are simple buttons , but with an interface of a Hyperlink control.

Okay... so where's the hyperlink "interface" .. I don't see it described in your article. Maybe you mean a hyperlink "appearance" .. but that is not an "interface."

Giorgi Moniava wrote:
If you had a better look at the article you would notice that this class does not even have a function similar to smth like SetURL(...).

Am I missing something? Sir, I've read your article through completely several times now.. The only functions described do cosmetic things like set a cursor, set underline, font color, etc... You are merely subclassing a button at this point -- however, it is still only a button (even if you make it look like hyperlink text). If that's all you are trying to achieve then your project is a "subclassed button" -- but there are hundreds of articles on subclassing buttons.

Understand, I'm not criticizing your project. If you were only trying to create a subclassed button with standard behaviors, but give it the appearance of "hyperlink" text, there is certainly nothing wrong with that -- but both your article and your comments made it sound that you were creating some new and unique way of "hyperlinking" -- and that apparently isn't the case.

So when John Doe downloads your code and includes in his project he just gets a button that looks like hyperlink text... but if he is actually wanting to hyperlink to something, the code is useless to him, unless he knows how to implement the shell functions.

So again... what's the point? ... I guess if you want to open a dialog from a control that looks like hyperlink, then this is the class for you.. Right?? Do I understand you now?

In business, if two people always agree, one of them is unnecessary.

That is what i wanted

I have not mentioned anywhere that i was creating a unique way of Hyperlinking , i said that i needed such buttons and could not find them on the net. And it is true, all articles here about Hypelinks ,are Hyperlink controls which are not buttons they are objects of CStatic derived classes who only take you to specified URL-s.

Yes you do Smile | :)

And it is very handy sometimes to use such Hyperlink buttons in your application . For example Visual Studio.Net uses such buttons , for example in the Wizard when creating a simple MFC or another application.

These are all simple `CStatic` derived Hyperlink controls who only take you to specified URL-s. `CHButton` is a `CButton` derived class which is a simple button , but with interface of Hyperlink control.

Which is by definition what a hyperlink is -- a control which takes you to a specified URL.

Giorgi Moniava wrote:

No, there is no "hyperlink interface." It's just a button... that's it -- a subclassed button with blue underlined text.

I think the confusion here Giorgi, is that you keep referring to this hyperlink interface. You may be using the term in the context of a GUI (graphical user interface). If so, you should specify GUI, because we normally think of GUI in relation to an application not a single button, and so to say "interface of Hyperlink control", sounds like you are referring to a programmatical interface which will render hyperlink behavior.

I think that is the primary source of confusion here with readers. You might want to consider rewording your article and it's subtitle to clarify the issue a bit -- eg. 'Hyperlink Appearance with Standard CButton Behavior'

In business, if two people always agree, one of them is unnecessary.

I did not know that "interface of Hyperlink control", meant a programmatical interface which rendered the hyperlink behavior. I wanted to say that it looked like a Hyperlink button and that's it. Anyway thanks, for your remarks i'll have that in mind in future. "Success is the ability of going from one failure to another with no loss of enthusiasm" - W.Churchill

Maybe you want to check those search results again; my particular implementation has been here for 2+ years! Smile | :)

Hello,
I have two suggestion for you, hope you don't mind it,
#1. Set Option for changing background color of button/hyperlink, though i implement that for myself, but for other user it will be benificial.

#2. Please check source, You had supplied with Article, It contain some minor compiler errors.
