Button3 Popup Menus

The following popup menus are invoked from the GFE:

Time Scale Popup Menu
Grid Manager Popup Menu
Spatial Editor Popup Menu
Legend Popup Menu
Spatial Editor Color Bar Popup Menu
Temporal Editor Popup Menu

Time Scale Popup Menu

Selecting MB3 over the Time Scale opens a submenu with the following items:

Select Grids by Time -- Lists the available Select Time Range(s). These time ranges can be defined in the Define Select Time Ranges under the Grids Main Menu. Selecting one of the Time Ranges listed sets the selected time range to it.
Select All Weather Elements -- Selects all Weather Elements in the Grid Manager.
Deselect All -- Deselects any Weather Elements and Time Ranges selected in the Grid Manager.

Grid Manager Popup Menu

The following items may appear when pressing MB3 over various locations in the Grid Manager. Some items apply to particular grids, or to Forecast versus Model grids, or to Weather Elements listed within the Grid Manager. The applicable items will be listed depending on where you press MB3. Some entries are not available at all times.

Menu Item	Description
Copy Grid	Make a copy of the grid and place it the copy buffer to be pasted to another location.
Paste Grid	Paste the grid in the copy buffer to the current location.
Fragment Grid	Divide the grid into the smallest duration possible. For example, a 12 hour temperature grid may be divided into 12 hourly grids. This applies only to Forecast database grids. This operation differs from the Fragment operation available in the GFE main menu. This MB3 Pop-up operation always fragments the entire grid identified by the current cursor location. The GFE main menu option uses the selected time range to fragment the portion of the grid selected. For more information on the Fragment operation available from the main menu, see the section on Fragment Grid in the Grid Manager Training Guide.
Split Grid	Divide the grid into two pieces at the nearest time constraint to the cursor location. Note that this operation differs from the Split operation offered in the GFE Grids-> menu. This operation uses only the current cursor location to divide the grid in exactly two parts. The other operation uses the selected time range to define the times at which to Split the grid. See the section on Split Grids in the GFE Grid Manager Training Guide for more information.
Assign <Default Value>	Resets the data in the grid to a default value. For WEATHER type grids, the default is no weather. For VECTOR type grids, the default is zero magnitude. For SCALAR type grids, the default is the weather element's minimum possible value as defined in serverConfig.py . For DISCRETE grids, it is the first-defined value in the serverConfig.py. The menu label indicates the default value, e.g., "Assign <NoWx>".
Assign <Pickup Value>	Sets the data in the grid to the current pickup value, while ignoring the vector edit mode and weather combine modes. The menu label indicates the current pickup value, e.g., "Assign 45"
Delete Grid	Remove the grid. This applies only to Forecast database grids.
Create From Scratch	Creates a grid at the point you selected. The grid is marked "e" for editable and the grid background is made green -- which specifies that the grid is locked by you. This applies only to empty Forecast database grids.
Undo	Reverses the last grid edit operation that was performed. You are only able to reverse the very last operation -- but you can undo the last Undo.
Select All Times	De-selects any Weather Elements first, then selects all times (from long in the past to far in the future) for the weather element where the pop-up action was initiated.
Display Info	The Display Info Dialog appears.
Clear Highlight	Erases any "highlights" that may be present. Note that certain smart tools can highlight grids.
"Smart Tools"	A set of smart tools (specified via gfeConfig) may appear. The default set is "Show_ISC_Area", "Show_ISC_Grid" and "Show_ISC_Highlight". These tools are described in the Intersite Coordination Training Guide.

Display Info Dialog

Opens a dialog window that displays information about the Weather Element, including the name, type, and edit state, and the Weather Element grids. You can close the dialog by selecting Cancel.

Spatial Editor Popup Menu

Selecting MB3 over the Spatial Editor opens a sub-menu with the following items:

A list of edit tools as defined in the GFE configuration file. Some of the basic tools that may appear are:

Assign_Value -- Assigns pick-up value to active edit area over active time range.
AdjustValue_Down -- Decrements grid points within the active edit area and time range by the Delta Value.
AdjustValue_Up -- Increments grid points within the active edit area and time range by the Delta Value.
Smooth -- Smooths grid points within the active edit area over the active time range.

Undo Grid Edit -- Reverses the last grid edit operation that was performed. You are only able to reverse the very last operation -- but you can undo the last Undo.
Undo Edit Area -- Reverses the last Edit Area operation that was performed in the Spatial Editor. You are only able to reverse the very last operation. You can undo the last Undo.
Legends -- Brings up a cascade menu allowing you to hide the legends, show the map legends, show all fcst legends, show just the active fcst legend, or show all weather element legends.
Select Homogeneous Area -- Selects an edit area of grid points whose values are within the weather element's Fuzz Value of the point at which MB3 was pressed. For example, suppose the Fuzz Value for T is 5 degrees and you press MB3 over a grid point that has a value of 60 degrees. The edit area selected will consist of those points that are contiguous with the point at which you pressed and have values between 50 and 70 degrees. Homogenous areas for WEATHER and DISCRETE type data consist of those areas that contain the same data value.
Deselect Contiguous Area -- Deselect the polygon of the active edit area which includes the point at which MB3 was pressed. For example, if the current edit area consists of two disjoint polygons and you press MB3 over one of them, it will disappear from the active edit area. This operation alters the active edit area.
Set Fuzz Value -- Brings up the Set Fuzz Value Dialog which allows the user to set the fuzz value that applies to selecting homogeneous areas. Applies only to SCALAR and VECTOR.
Vector Edit Mode -- Allows user to switch the vector edit mode between Magnitude Only, Direction Only, or Both components. Available only when a Vector weather element is the active element.
Weather Edit Mode -- Allows user to switch the weather edit mode between Combine and Replace modes. Available only when a Weather weather element is the active element.
Add ISC Marker -- Available when an ISC grid is directly displayed (clicking on the ISC grid). Adds an marker (similar to a sample, but without the data value display) at the popup location. Markers are used to indicate the ISC update time, site identifier, and official database symbol. Refer to the Intersite Coordination User's Guide for more details on markers. Depending upon the office type of the ISC grid, this adds the ISC marker to the appropriate marker set.
Remove ISC Marker -- Available when an ISC grid is directly displayed (clicking on the ISC grid) and when near an existing marker. Removes an marker (similar to a sample, but without the data value display) near the popup location. Refer to the Intersite Coordination User's Guide for more details on markers. Depending upon the office type of the ISC grid, this removes the ISC marker from the appropriate marker set.
Zoom to -- Change the X-direction of the Spatial Editor display to one of the several distances.

Legend Popup Menu

The Legend Area Button3 Pop-Up is position-sensitive -- the Pop-Up that is opened, and the commands it lists, pertain only to the particular Weather Element or Map whose legend you MB3-pressed over. The menu that opens allows you to:

Imaging -- Changes the Color Table of the Weather Element to one of several color enhancement curves. When you change the Color Table of a Weather Element, both it's Color Bar and it's display as image are changed accordingly. Also provides access to the color chooser.
Change Graphic Color to -- Changes the graphic color of the Weather Element or Map to the color you select. When you change the graphic color of a Weather Element, both its graphic display color and its Legend color are changed accordingly. Also provides access to the Color Chooser.
Line Width -- Changes the width of the lines that make up the contour, wind barb, wind arrow, or weather area.
Line Style -- Changes the texture of the line. Choices are: SOLID, DASHED, DOTTED, and DASH_DOTTED.
Density -- Changes the contour interval if the weather element is displayed as a graphic, much like the D2D system.
Magnification -- Changes the size of the contour labels for the selected weather element, the size of the wind barbs, or the label sizes for the map backgrounds.
Unload -- Unloads the Weather Element or Map from the GFE -- the Legend of the Weather Element and its display in the Spatial Editor are both removed.
Display As Image or Display As Graphic
Display Attributes -- The Spatial Editor Display Attributes Dialog appears.
Grid Ops -- Opens a cascade menu allowing you to do many of the same operations as you can on the grid manager pop-up.
Label - Appears only for Map Legends, and denotes the label attribute to appear for each of the map backgrounds.

The Grid Ops cascade provides the following capabilities; these operations apply to the weather element and grid identified by the legend:

Delete Grid -- Deletes the current grid.
Create From Scratch -- Creates a grid from scratch.
Delete Grid -- Remove the grid.
Fragment Grid -- Divide the grid into the smallest duration possible. For example, a 12 hour temperature grid may be divided into 12 hourly grids.
Assign Default Value -- Resets the data in the grid to a default value. For WEATHER type grids, the default is no weather. For VECTOR type grids, the default is zero magnitude. For SCALAR type grids, the default is the weather element's minimum possible value as defined in serverConfig.py . For DISCRETE type grids, the default is the first definition for the discrete key in the weather element definition in serverConfig.py. The menu label indicates the default value, e.g., "Assign <NoWx>".
Assign PickUp Value -- Sets the data in the grid to the current pickup value, while ignoring the vector edit mode and weather combine modes. The menu label indicates the current pickup value, e.g., "Assign 45".
Copy Grid -- Make a copy of the grid and place it the copy buffer to be pasted to another location.
Paste Grid -- Paste the grid in the copy buffer to the current location.
Display Info -- The Display Info Dialog appears.

Spatial Editor Color Bar Popup Menu

The color bar popup menu on the spatial editor changes depending upon the type of weather element displayed as an image. The menu that opens allows you to:

Fit to Data, brings up a submenu with several choices. Each changes the assignment of the color table spectrum so that the entire spectrum is scaled to the minimum to maximum data values found in the grids. These entries apply only to scalar and vector data.

All Grids - Uses the data values in all grids over the entire grid to determine the minimum and maximum values.
All Grids over Area - Uses the data values in all grids over the active edit area to determine the minimum and maximum values.
Single Grid - Uses the data values in just the current grid to determine the minimum and maximum values.
Single Grid over Area - Uses the data values in just the current grid over the active edit area to determine the minimum and maximum values.

Set Range -- Pops up the Set Color Table Range Dialog allowing the user to specify the minimum and maximum scaled values for the color table spectrum for the weather element currently displayed as an image. Applies to scalar and vector weather element types only.
Full Default Range -- Changes the scaling for the color table spectrum so that the entire spectrum is scaled from the minimum possible value to the maximum possible value. Applies to scalar and vector weather element types only.
Set Pickup Value -- Displays the Pickup Value Dialog for the currently active weather element.
Set Delta Value -- Displays the Delta Value Dialog for the currently active weather element.
Set to Recent Values --- Only used for WEATHER and DISCRETE type of weather elements. Displays a cascade of recently set pick-up values that were used with the Assign Value tool.
Set to Common Values -- Only used for WEATHER and DISCRETE type of weather elements. Displays a cascade of commonly used pick-up values. These are defined in the gfe configuration file's common weather values entry. Multiple levels of cascades may be configured.
Set to Session Values -- Only used for WEATHER and DISCRETE type of weather elements. Displays a cascade of user-set pick-up values. These values are added to this list from the Weather Set Value Dialog's Add to Session command. The purpose of this list is to allow the user to pre-configure a set of values that can be used again and again for the current GFE session.
Change Color Table To... -- Provides a list of color table spectrums that may be applied to the weather element displayed as an image. Also provides access to the Color Table Brightness Dialog and the Color Table Editor.

Spatial Editor Display Attributes Dialog

Opens a Display Attributes Dialog that displays the following information corresponding to the grid you selected:

Image Visual Type
Graphic Visual Type

You can change the settings of any of the attributes listed in the dialog and click OK. To close the dialog without making any changes, simply click Cancel.

The "image"-type visual cannot be turned off for the image mode. At least one graphic-type entry must be selected for the graphic mode.

Temporal Editor Popup Menu

Selecting MB3 over the Temporal Editor opens sub-menus that will differ depending on where you pressed. The following items may appear:

Menu Entry	Menu Location	Purpose
Display Attributes	Weather Element Label	The Temporal Editor Display Attributes Dialog appears. This applies only to Scalar and Vector data.
Undo	Data Area	Reverses the last grid edit operation that was performed. You are only able to reverse the very last operation -- but you can undo them last Undo.
Move Weather Element	Weather Element Label, Data Area	Appears if over a weather element label or data area. Moves the Weather Element to the top of the Temporal Editor display. The Move Weather Element Dialog opens that prompts you to confirm the move. This allows you to group Weather Elements into the same Temporal Editor data pane.
Full View	Weather Element Scale	Sets the temporal scale to the full range of values for the weather element.
Fit To Data	Weather Element Scale	Adjusts the scale to the minimum/maximum values of the grid data for the weather element.
Set...	Data Area	This applies only to WEATHER and DISCRETE data. Brings up the Temporal Editor Set Weather Pickup Value dialog allowing the user to set and edit the data.
Set to Recent Value...	Data Area	This applies only to WEATHER and DISCRETE data. Brings up a cascade of recently set pickup values. Choosing an entry will set the pickup value and edit the data.
Set to Common Value...	Data Area	This applies only to WEATHER and DISCRETE data. Brings up a cascade of commonly set pickup values. These values are defined in the GFE configuration file's common weather/discrete values entry.
