Hack Writer! | Tutorial_Help |
Now let's launch a bigger window than just a tiny little InfoBox. So we want to click on a graphic in Writer and have the option of saving the graphic/ picture to disk direct!
Cool! So what we would have to start out with is defining a identifier we will use throughout and we stick it in where all the other identifiers are located:
--- sw/inc/cmdid.h 2004-12-07 18:57:10.000000000 +0530 +++ sw/inc/cmdid.h 2004-12-21 19:08:39.000000000 +0530 @@ -159,6 +159,7 @@ Achtung: Ab sofort sind in diesem File k #define FN_GET_DOCSTAT (FN_FILE + 33) /* Dokumentstatistik einzeln auslesen */ +#define FN_SAVE_GRAPHIC (FN_FILE + 34) /* Save embedded graphic as */ #define FN_SAVE_SELECTION (FN_FILE + 35) /* Selektion speichern */
So that's going to be our identifier, next we qualify our identifier for what method to call when it is invoked, through whichever channel:
--- sw/sdi/_grfsh.sdi 2004-10-15 16:13:21.000000000 +0530 +++ sw/sdi/_grfsh.sdi 2004-12-21 20:15:52.000000000 +0530 @@ -85,6 +85,13 @@ interface BaseTextGraphic : Selection DisableFlags="SW_DISABLE_ON_PROTECTED_CURSOR"; ] + FN_SAVE_GRAPHIC + [ + ExecMethod = Execute ; + StateMethod = NoState ; + DisableFlags="SW_DISABLE_ON_PROTECTED_CURSOR"; + ] + SID_INSERT_GRAPHIC // zeigt auf FN_FORMAT_GRAFIC_DLG [ ExecMethod = Execute ;
There are also a whole lot of attributes that need to be defined for any slot that is used to hold a menu item or a toolbar item and these attributes are defined as Sfx...Items:
--- sw/sdi/swriter.sdi 2004-11-29 14:28:57.000000000 +0530 +++ sw/sdi/swriter.sdi 2004-12-21 19:13:45.000000000 +0530 @@ -3466,6 +3466,31 @@ SfxVoidItem GraphicDialog FN_FORMAT_GRAF ] //-------------------------------------------------------------------------- +SfxVoidItem SaveGraphic FN_SAVE_GRAPHIC +() +[ + /* flags: */ + AutoUpdate = FALSE, + Cachable = Cachable, + FastCall = FALSE, + HasCoreId = FALSE, + HasDialog = TRUE, + ReadOnlyDoc = FALSE, + Toggle = FALSE, + Container = FALSE, + RecordAbsolute = FALSE, + RecordPerItem; + Asynchron; + + /* config: */ + AccelConfig = TRUE, + MenuConfig = TRUE, + StatusBarConfig = FALSE, + ToolBoxConfig = TRUE, + GroupId = GID_GRAPHIC; +] + +//-------------------------------------------------------------------------- SfxVoidItem Grow FN_GROW_FONT_SIZE () [
With that, we are ready to use our brand new sfx item and we'll use it by adding it into the popup menu that is specified as MN_GRF_POPUPMENU in mn.src:
--- sw/source/ui/app/mn.src 2004-11-29 14:29:10.000000000 +0530 +++ sw/source/ui/app/mn.src 2004-12-21 20:28:27.000000000 +0530 @@ -945,6 +945,13 @@ Menu MN_GRF_POPUPMENU SEPARATOR ; MenuItem { + Identifier = FN_SAVE_GRAPHIC ; + HelpID = FN_SAVE_GRAPHIC ; + Text [ de ] = "~Grafik speichern..." ; + Text [ en-US ] = "Save ~Graphic..." ; + }; + MenuItem + { Identifier = FN_FORMAT_GRAFIC_DLG ; HelpID = FN_FORMAT_GRAFIC_DLG ; Text [ de ] = "~Grafik..." ;
That adds in the item to the menu and we still need to define what happens when it is clicked as we have specified in our handler that it invokes the Execute method, so we'll fill out the handler for this item in that method:
--- sw/source/ui/shells/grfsh.cxx 2004-12-07 18:57:35.000000000 +0530 +++ sw/source/ui/shells/grfsh.cxx 2004-12-21 22:19:53.684296352 +0530 @@ -217,6 +227,11 @@ void SwGrfShell::Execute(SfxRequest &rRe USHORT nSlot = rReq.GetSlot(); switch(nSlot) { + case FN_SAVE_GRAPHIC: + SaveGraphic(); + rReq.Ignore(); + break; + case SID_INSERT_GRAPHIC: case FN_FORMAT_GRAFIC_DLG: {
So we define a method called SaveGraphic that will be invoked when this item is clicked, and then the definition of the method:
--- sw/source/ui/shells/grfsh.cxx 2004-12-07 18:57:35.000000000 +0530 +++ sw/source/ui/shells/grfsh.cxx 2004-12-21 22:19:53.684296352 +0530 @@ -739,6 +754,20 @@ void SwGrfShell::GetAttrState(SfxItemSet } +void SwGrfShell::SaveGraphic() +{ + using namespace ::sfx2; + using namespace com::sun::star::ui::dialogs; + using namespace ::com::sun::star::uno; + + FileDialogHelper aDlgHelper( TemplateDescription::FILESAVE_SIMPLE, 0 ); + Reference < XFilePicker > xFP = aDlgHelper.GetFilePicker(); + aDlgHelper.Execute(); + + InfoBox( NULL, xFP->getFiles()[0] ).Execute(); +} + + SwGrfShell::SwGrfShell(SwView &rView) : SwBaseShell(rView)
Can you predict what the function does ? :-) As promised, it launches a dialog box that is definitely bigger than an InfoBox and then follows up with an InfoBox anyway :-D
For all these objects we have used, we need to declare them as well:
--- sw/source/ui/shells/grfsh.cxx 2004-12-07 18:57:35.000000000 +0530 +++ sw/source/ui/shells/grfsh.cxx 2004-12-21 22:19:53.684296352 +0530 @@ -137,6 +137,16 @@<br> #include <svx/tbxcolor.hxx><br> #endif +#ifndef _COM_SUN_STAR_UI_DIALOGS_XFILEPICKER_HPP_ +#include <com/sun/star/ui/dialogs/XFilePicker.hpp> +#endif +#ifndef _COM_SUN_STAR_UI_DIALOGS_TEMPLATEDESCRIPTION_HPP_ +#include <com/sun/star/ui/dialogs/TemplateDescription.hpp> +#endif +#ifndef _FILEDLGHELPER_HXX +#include <sfx2/filedlghelper.hxx> +#endif + #ifndef _FMTURL_HXX //autogen #include <fmturl.hxx> #endif
And we also have to declare the new method that we have added to the class in the class definition:
--- sw/source/ui/inc/grfsh.hxx 2000-10-05 17:04:19.000000000 +0530 +++ sw/source/ui/inc/grfsh.hxx 2004-12-21 19:24:14.000000000 +0530 @@ -71,6 +71,7 @@ public: void Execute(SfxRequest &); void ExecAttr(SfxRequest &); void GetAttrState(SfxItemSet &); + void SaveGraphic(); SwGrfShell(SwView &rView); };
So there stands the porting of the wonderful sd-save-image-context-menu as we plan to apply to Writer. We still need to extract the selected graphic out of Writer and save it to disk. If that is done, the patch would be complete :-)
Any takers ? :-)
But after understanding this, we can understand another hack on which this is based - the hack in Impress that allows the same capability, the difference being that it is complete! :-)
