Using the Terrasoft.AlignableContainer custom control

Glossary Item Box

Introduction

Starting with version 7.8 Creatio has a new custom control – the Terrasoft.AlignableContainer. This control is inherited from the Terrasoft.Container control and contains properties associated with a fixed container positioning relative to another controls.

Displaying the Terrasoft.AlignableContainer depends of the control used to position the container. In the absence of a control, the container is positioned in the center of the screen. The default order of container positioning is defined by the following sequence:

  1. The container displays under the control at first.
  2. If there is no space under the control, the container displays above it.
  3. If placing either below or above is impossible, the container displays on the right.
  4. If placing on the right is impossible, the container displays to the left of the control.

For the Terrasoft.AlignableContainer control you can also specify the background on which the container will be placed. These features of the Terrasoft.AlignableContainer control are applied in Creatio for positioning the mini page of the object.

Case description

When you click on a photo in the [Contacts] section, display an enlarged image with a background in the center of the screen. When hovering over a photo, display a larger version of the contact image relative to the photo container.

Source code

You can download the package with case implementation using the following link.

Case implementation algorithm

1. Create a replacing client module

Create a replacing client module and specify [Display schema – Contact card] (ContactPageV2) as parent object (Fig. 1). Creating a replacing page is covered in the “Creating a custom client module schema” article.

Fig. 1. Properties of the ContactPageV2 replacing schema

2. Add required methods to the page schema

  • openLargeSizeImage() – handler for clicking on the contact's photo to display the photo in the center of the screen.
  • openMiddleSizeImage() – handler for hover on the contact's photo to display the photo relative to the parent control.
  • setAlignToEl() – sets control near which the container needs to be displayed.
  • subscribePhotoContainerEvents() – creates a subscription to the mouse hover event.
  • onEntityInitialized() – an overridden base class method that performs actions after loading an object entity.
  • close() – hides containers with the photos.

3. Add the necessary configuration objects to the diff modification array.

To display image at the center of the screen add the Terrasoft.AlignableContainer custom control without parameters (do not specify a link on control near which you want to display the container as a parameter). Set the true value to the checkbox which is responsible for displaying the background for it to show up.

Pass parent control name to the Terrasoft.AlignableContainer container to to display a photo relative to the control.

Add a closing button to hide the image.

                var alignToEl = this.Ext.get(alignToElementId);

                }
            }
        ]/**SCHEMA_DIFF*/
    };
});

4. Define the CSS styles for displaying containers

In order to set the required dimensions of the displayed photo container, you need to define its CSS-style.

To do this, go to the [Configuration] section, and select [Add] > [Standard] > [Module] in the [Schemas] tab.

In module properties, set the title and header to "UsrContactPhotoContainerCSS” (Fig. 2).

Fig. 2. Module properties

Module styles are defined on the LESS tab (Fig. 3).

Fig. 3. The LESS tab of the module

Add the following CSS selectors:

.schema-wrap .photo-alignable-container::before, 
.schema-wrap .alignable-container-overlay::before {
    background: transparent;
}

.schema-wrap .photo-alignable-container.alignable-container {
    background: white;
}

.photo-alignable-container.middle-size-image-container {
    width: 250px;
    height: 275px;
}

.photo-alignable-container.large-size-image-container {
    width: 500px;
    height: 525px;
}

.photo-alignable-container .close-no-repeat-button {
    background-repeat: no-repeat;
}

.photo-alignable-container .close-button-wrapper:hover {
    background: transparent;
}

#ContactPageV2AccountLargeResizedPhotoContainerButton-image-view,
#ContactPageV2AccountResizedPhotoContainerButton-image-view
{
    height: 90%;
}

Save the schema, update the application page and clear the cache. A larger contact photo in the page center on a semi-transparent gray background will show up as the result (Fig.4). A larger contact photo will show up next to the main one as the result (Fig. 5).
