* * generic/tkImgPhoto.c (ImgPhotoSetSize): Only error-out if wedkf2002-10-091-40/+48
| | | | | | | | | fail to allocate a non-empty buffer; getting a NULL when we allocate an empty buffer is no problem since nothing will look at the value anyway. [Bug 619544] Also tidied up file to take into account the fact that we're using 32 bits per pixel in the master to accommodate the alpha channel as well as RGB.
* Applied companion patch for Tcl Patch 585105,dgp2002-08-051-7/+7
| | | | | | | | | | | | | | | | | | | | | updating Tk to use Tcl 8.4's fully CONST-ified interface, and fully CONSTifying Tk at the same time. This patch includes purging Tk of its last direct access to interp->result. [Bug 589853] The substantial changes include copying event sequence strings into Tcl_DStrings in tkBind.c, and copying [text] indices into Tcl_DStrings because parsing them involved overwriting them. If this causes performance trouble, that can be resolved by further converting them to Tcl_Obj's. The #defines USE_NON_CONST and USE_COMPAT_CONST have the same effect for Tk as they do for Tcl. (They actually change tcl.h)
* tests/visual_vv.test: Removed some dependence on [exec]ed utilitiesdkf2002-07-111-41/+129
| | | | | | generic/tkImgPhoto.c: Allowed photo image buffer allocation to fail more tests/imgPhoto.test: gracefully in some cicumstances. The remaining ones require API changes before they can fail nicely.
