Typedef Documentation

void Laxkit::ImageOutFunc

Simply oriented drawing of image to window.
Draw an image with upper left corner at window coordinates (ulx,uly). Positive y is down.

void Laxkit::ImageOutRotatedFunc

Drawing image to window with rotation and scaling.
Draw an image so that the upper left and right corners are at (ulx,uly) and (ulx+urx,uly+ury).

void Laxkit::ImageOutSkewedFunc

Drawing image to window with rotation, scaling, and skewing.
Draw an image so that the upper left and right corners are at (ulx,uly) and (ulx+urx,uly+ury), and the lower left corner is at (ulx+llx,uly+lly).

LaxImage *(* Laxkit::LoadImageWithPreviewFunc)(const char *filename, const char *pfile, int maxx, int maxy, char delpreview)

Loads an image, using a preview image.
If delpreview, then when the LaxImage is destroyed, the file at LaxImage::previewfile is deleted. Note that if an already existing preview is used (that is, no new one is generated), then delpreview reverts to 0, and the already existing preview is untouched in the destructor.

Function Documentation

int Laxkit::_laximlib_generate_preview ( const char * original,

const char * preview,

const char * format,

int width,

int height,

int fit

)

Generate a preview image. Return 0 for success.
WARNING: this does no sanity checking on file names, and will force an overwrite. It is the responsibility of the calling code to do those things, and to ensure that preview is in fact a writable path.

Todo:
*** afterwards, make sure preview was actually written

unsigned int Laxkit::composekey ( unsigned int k1,

unsigned int k2

)

From 2 keys, typically an ascii key and a dead key, compose another.
If k1 and k2 are not deadkeys and k1 and k2 are greater than 127, then 0 is returned.
If k2==0, then try to find a compose code for k1 on its own. In this case, if none is found, 0 is returned.
If both k1 and k2 are valid keys, and if the combination is not recognized, then k2 is returned.
This is used by anXWindow::CharInput().

void Laxkit::dab ( )

this empty function is for debugging purposes to allow breakpoints for the debugger to be encountered at strange places during program execution...

template<class T>

T* LinkedList<T> Laxkit::disconnectNode ( )

If this is part of a list, then remove it.
Connects prev_node to next_node if possible. Returns prev_node if it exists, or next_node otherwise. prev_node and next_node get set to NULL.

int Laxkit::eventscreen ( int e_type,

unsigned long mask

)

Check to see if some kinds of event types are in mask, and so allow them through.
Note that only KeyPress/KeyRelease/ButtonPress/ButtonRelease/MotionNotify/Enter/Leave/FocusIn/Out GraphicsExpose/Expose events are screened. All others pass right through.
Returns nonzero for allow event (not matched in mask), zero for reject event

unsigned int Laxkit::filterkeysym ( KeySym keysym,

unsigned int * state

)

Converts an Xlib keysym to a Laxkit key value.
This is called when Xutf8LookupString() returns a keysym but no buffer data. It is then assumed that the keysym corresponds to some control or function key.
If the keysym corresponds directly to a UCS value, then that value is returned. This happens when the keysym>0x01000000. The UCS value is then keysym&0x00ffffff.
If a keypad key is detected, then state is modified to have KeypadMask set.

Todo:
If the keysym corresponds to any of the keys in laxdefs.h, then it is mapped to those values. Otherwise...? CharInput() says if the returned value is > 0x1000000, then it is either a Laxkit value, or the X keysym plus 0x1000000, which is not quite how it is coded right now. need to check if the keysym can still be converted to a unicode value. keysyms correspond pretty well to it, and should have been converted to the buffer is event() if so, but not sure of that.

anXWindow * Laxkit::findsubwindow ( anXWindow * w,

Window win

)

Find the anXWindow having win, and ancestor w.
called from a loop over topwindows in run.
Perhaps this should be a window function?

int Laxkit::id_from_str ( const char * str,

char createifabsent = 0

)

Return the id associated with str.
If createifabsent!=0 and str is not known, then a new association is added, and the new id is returned.
If createifabsent==0 and the string is not known, then 0 is returned. No string can have 0 associated with it.

Todo:
*** make threadsafe

static int Laxkit::lark_position ( const char * str,

int * c

) [static]

Return the index in the lark_alpha_sorted stack that str would be found. If str is not there, then c is filled with that position in lark_alpha_sorted that the id of the lark must be pushed into.

Todo:
make this faster via binary search

void Laxkit::mapname ( char * buf,

int m

)

Todo:
be ablte use control, meta, and alt?

const char * Laxkit::str_from_id ( int id )

Return pointer to string associated with id, or NULL if none.
Yes, lark is a take off on Glib's quarks: Laxkit+quARK.
Laxkit maintains a hash of strings and associated ids, that can be used as a shortcut for checking string equality for commonly used strings.

Todo:
*** these ultimately will replace X Atoms for the basic message types. Using X Atoms leaves lots of silly residue in the X server after programs end.
*** make threadsafe

double * Laxkit::transform_from_3x3_fixed ( double * result,

int M[3][3]

)

Create as possible an affine transform from M, which has 16.16 fixed point elements.
If result is NULL, then create and return a new double[6].
This is mainly to assist in using XTransform in the XRender extension, which allows full 3x3 transformations.
[ a b 0 ] M=[ c d 0 ] --> [a b c d tx ty] [ tx ty 1 ]

void Laxkit::transform_to_3x3_fixed ( int M[3][3],

double * m

)

Fill result with the affine transform m.
Note that if result is NULL, you will crash your program.
