SWMM5 Delphi GUI Fstatus.pas Summary

 Below is a high-level summary of Fstatus.pas, the Delphi unit that implements the TStatusForm in SWMM. This form is used to display the Status Report (a text-based summary of the SWMM simulation run).

---

1. Purpose

Fstatus.pas defines the TStatusForm, an MDI child form that:

1. Loads and displays the text content of a temporary Status Report file produced by the SWMM engine.
2. Offers functionality to copy the text to the clipboard or to an external file.
3. Supports printing the text contents to the printer or a preview window.

2. Key Components

1. Memo1 (TMemo):

   • Displays the text lines of the Status Report.
   • Can be scrolled to see the entire report.

2. Methods:

   • RefreshStatusReport:
     Opens the temporary report file (TempReportFile) in text mode.
     Reads all lines and loads them into Memo1.Lines.
   • ClearReport:
     Clears the Memo so the text is empty.
   • CopyTo:
     Launches the CopyTo dialog to let the user copy the report to the Windows clipboard or to a file.
   • Print:
     Prints the textual content of the Status Report through the main form’s printer object.

3. Overall Flow

When SWMM completes a simulation, it writes a Status Report to a file. The TStatusForm:

1. Refresh: Reads that file and populates Memo1.
2. The user can copy the textual contents or print them from the form’s UI.
3. Once the user closes the form, it frees itself (in typical MDI child fashion).

In summary, Fstatus.pas provides a simple text viewer form (TStatusForm) for SWMM’s Status Report, with basic capabilities to display, copy, and print the simulation’s textual run results.
