I would like to ask if I should modify dlls/x11drv/x11drv_main.c, in process_attach(), continue the call of TSXOpenIM(display, NULL, NULL, NULL); XRegisterIMInstantiateCallback(...,im_callback,...); and in my callback function: im_callback() { XOpenIM(); ...

Re: ImageList fixes

by daveh-wine＠cadlink.com

From: mstefani(a)redhat.de >> The hotspot handling in imagelist is broken. This fix partially >repairs it. >... and breaks it too. With your patch the hotspot handling in It was a crude attempt to differentiate between the subtle difference in meaning of the hotspot passed in to BeginDrag and that passed in to SetDragCursorImage. The BeginDrag hotspot sets the position of the image wrt the current mouse position and also sets the hotspot there. Subsequently calling SetDragCursorImage does not physically move the image, but changes the mouse messages to reflect the offset. We probably need to do more substantial logic and track both hotspots independantly to achieve better Windows emulation. The bHSPending can be removed as it was only there to prevent the image moving as a result of a call to SetDragCursorImage after BeginDrag with different hotspots. If this breaks my application too much I'll do a more thorough fix and test more widely. Dave Hawkes

linux from scratch

by Shane Shields

Never underestimate the power of stupidity and naievity, especially as projects like 'Linux from scratch' are getting popular. FYO i built my system using linux from scratch and it runs better than the redhat 6.2,7.1,7.2 distributions (insert preferred dist) no core dumps AT ALL. my directorys are posixs standard and i know more about linux than someone who just puts in a cd and answers some questions and ends up with some flakey bloatware. a stupid or naieve person CANNOT install linux from scratch but they can from a redhat cd. everybody can drive a car but not everyone can fix or build one.

how to handle large wineserver request structure ? I've been working on adding the dwFillAttribute handling to CreateProcess (and passing between parent and child) while I was at it, I also added all the other fields (window geometry, console title/size...) at the end the two requests used in the process (new_process and init_process) are larger than the fixed request_max_size structure (80 bytes would be needed) so, what's the preferred way of handling this: 1) bump the request_max_size to the needed size (but all requests will be penalized about it) 2) remove the request_max_size (therefore aligning the size of the request on the one of the biggest available) 3) try to compress the structure fields (most of the data are 32 bits, whereas they would fit in 16 bit fields) 4) store the data above the 64 bytes into the variable part of the message (but that would break the current structure scheme) A+
