Hi All,
After a long time, I got some time to refine/correct the patch.
Please find the WIP patch for "Printing Support in frmQuery (QueryBuilder/Graphical Query Builder(GQB)/Explain) & Save as an image".
Modified/Added file list and explanation are given below:
Print support on Gtk (Linux)
* xtra/wx-build/build-wxgtk
- We have to modify this script, added few new flags) to enable printing on Gtk.
Please follow these links for more details:

Print support/Save as an image in Explain window
* pgadmin/ctl/explainPrintout. cpp (Added)
- Definition for the new introduced class - ExplainPrintout
- A helping class for support for the printing the explain
* pgadmin/gqb/gqbPrintout.cpp (Added)
- Definition for the new introduced class - gqbPrintout
- A helping class for support for the printing the GQB
* pgadmin/ctl/explainCanvas.cpp
* pgadmin/include/ctl/ explainCanvas.h
- Added new function ExplainCanvas::SaveAsImage( filename) to save Explain as an image (bmp for now)
- Removed a unused variable lastShape
Print support for the Query window
* pgadmin/include/ctl/ctlSQLBox.h
* pgadmin/include/frm/frmQuery.h
* pgadmin/include/gqb/gqbViewController.h
* pgadmin/frm/frmQuery.cpp
* pgadmin/gqb/gqbController.cpp
Print support/Save as an image in GQB
* pgadmin/include/gqb/gqbEvents.h
* pgadmin/include/gqb/gqbGraphSimple.h
- I had to use wxMemoryDC instead of wxBufferedDC to enable printing
* pgadmin/include/gqb/ gqbGraphBehavior.h
* pgadmin/gqb/gqbGraphSimple.cpp
* pgadmin/gqb/gqbView.cpp
- Change the function definition drawAll(wxBufferedDB& bdc) to drawAll(wxMemoryDC& bdc, bool adjustScrolling)
- Using the same function to draw on PrintDC/PrintPreviewDC and Canvas.
- In case of PrintDC/PrintPreviewDC, we do not need this function to adjust the scrolling according to the canvas
- Introduced a new variable modelSize to take care of the total size of the Model (Model consists of tables & Joins)
- Introduced a new function updateModelSize(...) to update the model size on demand
Data/Project Initialization & new menu declaration
* pgadmin/include/frm/menu.h
* pgadmin/include/utils/ sysSettings.h
* pgadmin/pgAdmin3.cpp
- Initialize the Print objects for Query/Explain/GQB.
pgAdmin Build addition (Added new files)
* pgadmin/pgAdmin3.vcproj
* pgadmin/gqb/module.mk
* pgadmin/ctl/module.mk
I have tested this patch on linux (Ubuntu having libgnome installed), Window Vista and Mac 10.5.
I am having couple of problems with this patch.
1. On OSX (Mac):
- If I see a print preview for any of Query/Explain/GQB, it works perfectly.
But, when we close the Print-Preview dialog, the query dialog is not getting enabled.
Something is missing, but I am not able to figure out the same.
2. On all the platforms:
- If I call the new function updateModelSize(...), when we add new table to the model.
- In this case, after selecting a table/view from the left size tree (browser), if I click couple of times (five-six times), then the program is getting crashed.
- I tried to use the mutex/Semaphore, but it was still not working. :(
(For the same reason, I have not added the updateModelSize(...) function, while creating/deleting a table/view, in this patch)
Can anybody please help on this?
