The Edit Image dialog can displayed by either double clicking anywhere within an image form field object or selecting the image field and clicking on the "attribute edit" icon in the tool bar. This dialog presents the current attributes of the image field. The dialog consists of three sections: identification, appearance, and properties.
This section displays naming and other identifying information for the image form field object.
| Field Name | This field contains the name of the image field. The Screen Painter automatically generates a unique name for it. This name can be maintained or changed, as long as the new name conforms to the Zim Object Naming Rules. |
| Form Name | This field contains the name of the form in which the image field was created. The field can be viewed by selecting it and scrolling left and right, but its value cannot be changed. |
| Directory | This field contains the name of the Zim directory that owns the form in which the image field was created. The field can be viewed by selecting it and scrolling left and right, but the value cannot be changed. |
| Field Number | This field contains an automatically generated identifying number for the image field. The value in this field can be used to identify the image field if it triggers a callback event. Refer to Form Fields and Callback Events for more detailed information about associating form fields with callback events. The value in this field can be changed and need not be unique. |
| Field Tag | This field contains an identifying text string for the image field. The value in this field can be used to identify the image field if it triggers a callback event. Refer to Form Fields and Callback Events for more detailed information about associating form fields with callback events. The value in this field can be changed and need not be unique. If left blank (the default), the value contained in Field Name is used for Field Tag. |
| Help Message | This field contains the text to display in an field of type "message" (if one exists in the form) when the image field receives the input focus. The message that appears at the bottom left of this dialog is itself a "message" field, and the help message associated with each field in the dialog is automatically displayed there when the field receives the input focus. If you intend to have a "message" field in your forms, enter an appropriate help message text in this Help Message field. |
This section presents the display or appearance attributes of the image form field object.
| Visible | This field determines if the image field is visible by default. The visibility attribute of all form fields other than labels and graphics can be dynamically modified under Zim program control. |
| Pointer Style | This field is used to select the pointer (or cursor) style to use when the pointer is over or in the image field, and the image field is available. By default, the value is "default", which for a image field, is the "Arrow" pointer style. |
| Image / Image Type | This field is used to select from the three supported image file types, "Bit Map", "(Windows) Meta File", and "Icon". |
| Image / Auto Size | This field is used to select from four different automatic image sizing options. These are "None-clipped", "Image to object", "Image proportional" and "Object to image". Refer to Image Auto Size Options for more detailed information about the different automatic image sizing options. |
| Image / Image File Name | This field is applicable only to "Image" type push buttons. It contains the full path name of the file which contains the image which is to appear in the image field. Refer to File Path Prefix Characters for information about the directory path prefix characters available within the painter and within Zim itself. |
| Image / Select | This push button invokes the Windows "File/Select" common dialog with the caption Select Image File, and places the contents of Image File Name in the File Name field. If Image File Name is prefixed by one of the special file path prefix characters, then the directory list is positioned within the appropriate directory. Otherwise the directory list is positioned within the directory specified by the full path name of Image File Name. If the file selected from this dialog is located in one of the special directories, its directory path name is replaced by one of the file path prefix characters. Otherwise, the full path name of the file is preserved. |
This section presents the behavioral attributes of the image field.
| Availability | This field determines the "availability" attribute of the image field. The values are "Available", "Unavailable", "Guarded" and "Protected". Refer to Form Field Availability Attributes for a more detailed description of the characteristics of these different availability values. |
| Tab Stop | This field determines if the image field is included in the tab order. If cleared, the end-user is not able to access this field by using the tab keys. The image field is still directly accessible by accelerator keys and the mouse. |
| Tab Index | This field contains a number which represents the relative position of the field in the tab sequence order. A value of zero (0) means use the tab sequence order as defined by the relative position of the field in the structure chart. |
| OK | This push button performs any required data validation, commits any changes that were made in this dialog, and returns to the Screen Painter's layout mode. |
| Cancel | This push button discards any changes that were made in this dialog and returns to the Screen Painter's layout mode. |
| Help | This push button invokes the Zim Help facility, initially displaying the section entitled Edit Image dialog (this section). |
| Options | This push button displays the Image Options dialog that enables additional attributes of the image to be viewed and/or modified. |
