Function Documentation

bool EnsureFileDirectoryExists	(	wxFileName *	aTargetFullFileName,

		REPORTER *	aReporter = `NULL`
	)

Helper function EnsureFileDirectoryExists make aTargetFullFileName absolute and creates the path of this file if it doesn't yet exist.

Parameters

aTargetFullFileName	the wxFileName containing the full path and file name to modify. The path may be absolute or relative to aBaseFilename .
aBaseFilename	a full filename. Only its path is used to set the aTargetFullFileName path.
aReporter	a point to a REPORTER object use to show messages (can be NULL)

Returns: true if aOutputDir already exists or was successfully created.

bool EnsureTextCtrlWidth	(	wxTextCtrl *	aCtrl,
		const wxString *	aString = `NULL`
	)

Function EnsureTextCtrlWidth sets the minimum pixel width on a text control in order to make a text string be fully visible within it.

The current font within the text control is considered. The text can come either from the control or be given as an argument. If the text control is larger than needed, then nothing is done.

Parameters

aCtrl	the text control to potentially make wider.
aString	the text that is used in sizing the control's pixel width. If NULL, then the text already within the control is used.

Returns: bool - true if the aCtrl had its size changed, else false.

wxConfigBase* GetNewConfig ( const wxString & aProgName )

Function GetNewConfig.

Use this function instead of creating a new wxConfig so we can put config files in a more proper place for each platform. This is generally $HOME/.config/kicad/ in Linux according to the FreeDesktop specification at http://standards.freedesktop.org/basedir-spec/basedir-spec-0.6.html The config object created here should be destroyed by the caller.

Parameters

aProgName is the name of the program calling this function - can be obtained by calling Pgm().App().GetAppName(). This will be the actual file name of the config file.

Returns: A pointer to a new wxConfigBase derived object is returned. The caller is in charge of deleting it.

static int KiROUND ( double v )

KiROUND rounds a floating point number to an int using "round halfway cases away from zero".

In Debug build an assert fires if will not fit into an int.KiROUND: a function so v is not evaluated twice. Unfortunately, compiler is unable to pre-compute constants using this.

int ProcessExecute	(	const wxString &	aCommandLine,
		int	aFlags = `wxEXEC_ASYNC`,
		wxProcess *	callback = `NULL`
	)

Function ProcessExecute runs a child process.

Parameters

aCommandLine	The process and any arguments to it all in a single string.
aFlags	The same args as allowed for wxExecute()
callback	wxProcess implementing OnTerminate to be run when the child process finishes

Returns: int - pid of process, 0 in case of error (like return values of wxExecute())

Round to the nearest precision.

Try to approximate a coordinate using a given precision to prevent rounding errors when converting from inches to mm.

ie round the unit value to 0 if unit is 1 or 2, or 8 or 9

wxString SearchHelpFileFullPath	(	const SEARCH_STACK &	aSearchStack,
		const wxString &	aBaseName
	)

Function SearchHelpFileFullPath returns the help file's full path.

Return the KiCad help file with path and extension. Help files can be html (.html ext) or pdf (.pdf ext) files. A <BaseName>.html file is searched and if not found, <BaseName>.pdf file is searched in the same path. If the help file for the current locale is not found, an attempt to find the English version of the help file is made. Help file is searched in directories in this order: help/<canonical name> like help/en_GB help/<short name> like help/en help/en

Parameters

aSearchStack	contains some possible base dirs that may be above the the one actually holding aBaseName. These are starting points for nested searches.
aBaseName	is the name of the help file to search for,

without extension

.

Returns: wxEmptyString is returned if aBaseName is not found, else the full path & filename.
