The purpose of the Show or Hide Objects dialog box is to allow the user to change which objects (points, lines, and polygons) are visible in the main working area. It can also be used to select and edit objects. The Show or Hide Objects dialog box is displayed by selecting Object|Show or Hide Objects… The user can continue to work with the model while this dialog box is visible. The names of the objects are displayed on the terminal branches of a tree control. Before the name of each object is a check box. The check box will be checked if the object is visible and unchecked if the object is hidden. The user can check or uncheck a check box next to an object’s name to show or hide that object.
Hiding objects does not deactivate them; it just makes the working are less cluttered. A typical reason to show some objects but not others would be to display only the objects that affect a particular data set. For example, to display only the objects that affect the Kx data set, the user would uncheck the check box next to "All Objects" to hide all the objects and then check the check box for "Kx" under "Data Sets" to show all the objects that directly affect Kx.
In addition to a check box, the main branches of the tree also have a plus or minus sign. The symbol will be a plus if the branch is open to display its sub branches or a minus if the branch is closed so that its sub branches are hidden. If the user clicks on this symbol, the branch will switch between the opened and closed state.
The check boxes before the main branches will either checked, unchecked or grayed. A check box will be checked if all the branches beneath it are checked. It will be unchecked if all the branches beneath it are unchecked. It will be grayed if some of the branches beneath it are checked and others are unchecked. If the user checks or unchecks the check box for one of the main branches, it will show or hide respectively all of the objects for the branches beneath it. If all of the objects beneath it are already visible, they all will be hidden. If any of the objects beneath it are hidden, they all will be made visible.
The main branches are labeled
All the objects are listed under "All Objects". All the objects used to set the size of the grid cells are listed under "Set Grid Cell Size". In addition, the value the user has specified for the cell size will be displayed in parentheses after the name of the object. All the data sets are listed under "Data Sets". Beneath each data set in "Data Sets" are listed all the objects that directly set the values of the data set. The formula used for each data set will be displayed in parentheses after the name of the object. All the boundary conditions are listed under "Boundary Conditions". Beneath each boundary condition in "Boundary Conditions" are listed all the objects that directly set the values of that boundary condition. Any objects that are not used to set the size of grid cells, or to set the value of one or more data sets or boundary conditions are listed under "Unused Objects".
The user can select or edit objects by right-clicking on the name of the object and selecting “Select” or “Edit” from the popup menu. The user can also edit an object by double-clicking on its name. When the user selects “Select”, the object will become selected in the main GoPhast window and all other objects will be deselected. If the user selects “Edit” or double-clicks on an objects name, the Object Properties dialog box (p. 49) will be displayed so the user can edit the object.
