Creating Toolbars Example

In the following example, a simple three-button toolbar is created with two standard buttons separated by a separator. A separator provides a small gap between groups of buttons and does not receive user input. The toolbar images are loaded into an image list, which is created by calling the ImageList_Create() function. Images can be loaded from a bitmap using LoadImage() or by using one of the standard system image sets with the TB_LOADIMAGES message. The image list is then attached to the toolbar using the TB_SETIMAGELIST message. Each button’s associated image is specified by the iBitmap member of the TBBUTTON structure. Clicking either button generates a message box indicating which button was selected. In order for the toolbutton image to be displayed correctly the image icons will need to be downloaded and placed into the project directory alongside the cpp file.
