The Сbmp Button Transparent class and examples were developed for a competition. This class enables the handling of cursor hover and button press actions on free-form buttons.Also recommended: On Balance Volume (OBV) Indicator Class - similar library with strong performance on MetaTrader 5.
The button is created using the standard CButton object, with images set for four states: normal, hovered, pressed, and hovered-pressed. The button shape is determined by analyzing the default state image (normal button), where a set of free-form regions with non-zero transparency is considered the button. The button shape can be complex, and the implementation supports various anchor corners and chart subwindows.
The archive includes the button class and three examples:
- Buttons on a chart without a dialog box, allowing customization of anchor corner and 1st point coordinates.
- Buttons in an expert advisor dialog box.
- Buttons in an indicator dialog box.
The library supports various button types, which can be set using the locking() function. It uses a transparency threshold of 250 and works with BMP images in 32-bit format (A8 R8 G8 B8). Images should be loaded as resources, as demonstrated in the examples.
