Hyperlink

Created: 08.06.2017 | Updated: 18.06.2017

The Hyperlink dialog.

Summary

This dialog allows the designer to specify the properties of a Hyperlink object. A hyperlink is a non-electrical drawing primitive. Similar to a text string, it can be placed anywhere on a sheet. Where it differs is in its ability to link to a web page, or to a document on a local or shared drive, through specification of a target URL. This offers a fast, convenient alternative when providing access to datasheets for components used in a design. A hyperlink object can also provide a beneficial link to your own organization's website, within the title blocks of your schematic source documents.

For information on how a placed hyperlink object can be modified graphically, directly in the workspace, see Graphical Editing.

Access

The Hyperlink dialog can be accessed prior to entering placement mode, from the Schematic – Default Primitives page of the Preferences dialog. This allows the default properties for the hyperlink object to be changed, which will be applied when placing subsequent hyperlinks.

During placement, the dialog can be accessed by pressing the Tab key.

While attributes can be modified during placement, bear in mind that these will become the default settings for further placement unless the Permanent option on the Schematic – Default Primitives page of the Preferences dialog is enabled. When this option is enabled, changes made will affect only the object being placed and subsequent objects placed during the same placement session.

After placement, the dialog can be accessed in one of the following ways:

  • Double-clicking on the placed hyperlink object.
  • Placing the cursor over the hyperlink object, right-clicking and choosing Properties from the context menu.
  • Using the Edit » Change command and clicking once over the placed hyperlink object.

Options/Controls

  • Color - click the color sample to change the text color, using the standard Choose Color dialog.
  • Location X/Y - the current X (horizontal) and Y (vertical) coordinates for the bottom-left corner of the hyperlink's bounding rectangle (when placed with zero rotation). Edit these values to change the position of this corner in the horizontal and/or vertical planes respectively.
  • Orientation - specify the orientation of the hyperlink, counter-clockwise in relation to the horizontal. Options available are: 0 degrees, 90 degrees, 180 degrees, 270 degrees.
  • Horizontal Justification - specify how the hyperlink is to be horizontally justifed. This will depend on its current Orientation and Location X/Y. The following justification options are available, using a placed hyperlink with 0 degrees orientation as an example:
    • Left - the left edge of the hyperlink's bounding rectangle is against the X = Location X line.
    • Center - the hyperlink's bounding rectangle is centered across the X = Location X line.
    • Right - the right edge of the hyperlink's bounding rectangle is against the X = Location X line.
  • Vertical Justification - specify how the hyperlink is to be vertically justifed. This will depend on its current Orientation and Location X/Y. The following justification options are available, using a placed hyperlink with 0 degrees orientation as an example:
    • Top - the top edge of the hyperlink's bounding rectangle is against the Y = Location Y line.
    • Center - the hyperlink's bounding rectangle is centered across the Y = Location Y line.
    • Bottom - the bottom edge of the hyperlink's bounding rectangle is against the Y = Location Y line.
  • Mirror - enable this option to flip the hyperlink across an axis that depends on its current Orientation and Location X/Y.
When the hyperlink object is mirrored, this simply means the location of the text may shift by virtue of mirroring the bounding rectangle. The text itself is not mirrored, and will always remain readable.

Properties

  • Text - use this field to directly enter the required link text; the text that is displayed on the sheet. Special strings appear in the format =<ParameterName>. They are derived from parameters defined at the document and/or project level, a listing of which is available from the associated drop-down. Parameters can also be defined at the variant level. Such a parameter can be referenced using the special string notation (i.e. =<VariantParameterName>). The value of the parameter will only be displayed when the associated variant for which it is defined, is made the current variant.
Document-level parameters are defined on the Parameters tab of the Document Options dialog (Design » Document Options). Project-level parameters are defined on the Parameters tab of the Options for PCB Project dialog (Project » Project Options). Variant-level parameters are defined in the Edit Project Variant dialog.
  • URL - the target web page. Simply type-in the URL directly, or copy and paste the address from your browser. To confirm correct address, simply click the  control. This will open the target URL as a tabbed document inside Altium Designer.
You don't need to enter the full URL with http:// prefix. Entering the short-form address for a website will also work, for example www.altium.com, or altium.com. Also, when targeting a local document on your hard drive or a shared drive, simply use the prefix file:/// – for example file:///C:\Datasheets\ExampleDatasheet.pdf.
  • Font - this control serves two purposes. Firstly, it reflects the currently chosen font for the text in terms of Font Name, Font Size and Font Style. Secondly, when clicked it provides access to the standard Font dialog, from where to change the font as required.
Effects are also displayed when enabled (Strikeout, Underline). If Regular is used for the font's style, this will not be displayed visually in the control's string.
  • Locked - enable this option to protect the hyperlink from being edited graphically.
If attempting to graphically modify an object that has its Locked property enabled, a dialog will appear asking for confirmation to proceed with the edit. If the Protect Locked Objects option is enabled on the Schematic – Graphical Editing page of the Preferences dialog, and the Locked option for that design object is enabled as well, then that object cannot be selected or graphically edited. Double click on the locked object directly and disable the Locked property, or disable the Protect Locked Objects option, to graphically edit the object.
