An Image Button is similar to a Button. In fact, it's an Image with the "Button Effect" property set to "Second Image". Unlike Buttons, Images can display image files. You can change the displayed image in runtime. You can also link an Image to the Database. An Image can interact with the user through its Events. You should use an Image Control to create a stylish button or to display image files. Value - Its value is the full path of the displayed image.
It's possible to perform drag-n-drop of an image file ("BMP", "GIF", "PCX", "JPG", "PNG") into an Image Button Control to define it. image.
It's also possible to drag-n-drop two images onto an Image Button. The Control will have the Effect = Second Image automatically with the two images assigned by their selected order.

The window presents the resources for the project that are in use as icons, images or other resources, in this case, images.
In the central area there is a visualization of the image that we can use in the form. We can add or delete images from the list that appears in this window. In addition, in the upper right corner is a tool that allows you to gradually change the background to better perceive images that have a transparent background or that are white, with a transparent background.
Finally, you can also search for existing images associated with the project.
When choosing the tab to choose icons, the system presents a new window where you can choose system icons divided by categories and / or graphic styles. After choosing, it switches to the base screen of this tab.
