Introduction to Chtslider control bar control class of Htcontrol control class in VC + + _c language

This article describes a control bar control class file code in the Htcontrol control, which is completely self-contained and has no base class. Implemented directly by the WIN32 API. You can use it in sdk,mfc,wxwidget and so on. Control includes a vertical joystick control, which is used in exactly the same way as the horizontal one. The form must be created dynamically, with specific code snippets as follows:

M_htsliderr.create (130, M_hwnd, ichildid++, 0, 9);
M_htsliderr.setbgpic (_t (". \\pic\\SliderBg.png"), NULL, 5, 5);
M_htsliderr.setthumbpic (_t (". \\pic\\SliderThumbN.png"));
M_htsliderr.setmouseonthumbpic (_t (". \\pic\\SliderThumbH.png"));

Easy to use, can be considered to be a window is a C + + object, to implement a function of direct call interface, there is no additional code. Here is the main file code for the joystick class:

In addition, the Chtslider control bar class also has flexible interface performance, form arbitrary transparency changes, such as the use of the following interface to achieve transparency changes:

void settransparency (int itransparency);

I hope the code described in this article can be a certain help for VC + + project development.
