It uses the cairo "Render" monad. You should be able to replace "onExpose" events with something like... someWidget `on` draw $ do moveTo 0 0 lineTo 10 10 The patch also adds "Region" and "RectangleInt" cairo types. If you have time, please try it out and let me know if it works ok for you.

I have some code that works with GTK2, but would like to bring it up to date. Most everything I've figured out, except the best way to replace the `renderWithDrawable` function. If I have a DrawingArea (or the corresponding DrawWindow) what is the best way to draw to it directly? I see various bits of information about a "draw" callback and surfaces, but nothing that has been entirely clear to me. Thanks in advance. ------------------------------------------------------------------------------ Everyone hates slow websites. So do we.

It seems like icon loading failed for some reason but how do I troubleshoot that? I've checked the icon file - it's there and it's correct. Is there way to know what exactly imageNewFromFile is unhappy about? I see following error in console: Gtk-CRITICAL **: gtk_box_pack: assertion `child-&gt;parent == NULL' failed but I'm not sure how to relate it to particular place in my code :( I'm not even sure if this error related at all - upon app exit I got another one: Gtk-CRITICAL **: IA__gtk_window_group_remove_window: assertion `window-&gt;group == window_group' failed and it doesn't make any sense either. cheers, Max.</pre> Max 2013-02-07T15:50:24 http://comments.gmane.org/gmane.comp.lang.haskell.gtk2hs/3104 <pre>Version Control --------------- Harald and Stephan's Version Control integration has been merged in! If you want to help out on this there are still some cool things that could be added. I for one would love something to show my changes vs. the repo as I edit. Harald and Stephan also added a number of other nice UI changes. Unfortunately I do not have a list (but my favourite is that selecting some text highlights other occurrences). Better Haddock and GHCi support ------------------------------- While writing documentation for jsc, I made a few changes to help make writing Haddock docs easier.... * Documentation pane - New pane that uses WebKit to display your packages Haddock docs (Package -&gt; Open Documentation). * Auto build Haddock docs - If you click the tick button on the toolbar it will automatically build your docs and reload the Documentation pane while you edit your code. If you have background build switched off then Ctrl+B will run tests and build docs if the tick is on.</pre> Hamish Mackenzie 2013-02-02T16:48:24 http://comments.gmane.org/gmane.comp.lang.haskell.gtk2hs/3103 <pre>Hi, I want to do a release of Leksah to Hackage that uses Gtk3 and WebKit (preferably in the next week or two). This will need the following patches: https://patch-tag.com/r/hamish/gtk2hs http://leksah.org/gtksourceview3.patches (repo still seems to be darcs1) https://patch-tag.com/r/hamish/webkit Although these packages default to gtk3 you can still use them with gtk2 (cabal install -f-gtk3) I think we have three options: 1) Push the Gtk3 patches into the Gtk2Hs repo in preparation for a regular release (perhaps 0.13.0). 2) Create a new repo for them and release it as gtk on Hackage (version 1.0.0 or 0.13.0) and continue merging 0.12 repo changes in. 3) Add gtk-gtk3, gtksourceview-gtk3 and webkit-gtk3 to Hackage. Please can we start the ball rolling on option 1 or can you let me know which of the other two options you would prefer?

I am having difficult in modifying the font of a widget to underline. How can it be done? I am also not sure if font underline is the best solution for my problem. So I would like to have some advices. Basically I have a set of options that can be multiply marked, and they should be ordered. I want to display them horizontally, to make better use of space of the container. Each option is being rendered as a toggle button widget. The label of the button describes what the option is. The status of the toggle button tells if the option is marked or not. To order the options I keep the notion of a current "selected" button, together with two additional "controll" buttons that allow repositioning the selected button in the list: one to move the selected button to the left and another to move the selected button to the right. +---+ +-----+ +----+ +-----+ +-----+ +----+ +--+ | &lt;-| |xOPTA| |OPTB| |xOPTC| |xOPTD| |OPTE| |-&gt;| | | | | | | |-----| | | | | | | +---+ +-----</pre> José Romildo Malaquias 2012-12-19T08:41:20 http://comments.gmane.org/gmane.comp.lang.haskell.gtk2hs/3072 <pre>I would like to have a CellRenderer which displays a multi-line text in a tree view.

Gtk expects callbacks to be 'IO ()' functions, while I would like them to be 'StateT X IO ()', with X a global state that lives through the whole program life. When registering a callback, I have to wrap it with runStateT or use MonadControl tricks to thread the current state to the callback while keeping the 'IO ()' signature: or However, this won't actually have the correct behavior: * 'callback' will always read X as it was at register time, and not at trigger time; * all modifications to this X instance are lost when leaving 'callback'. Basically, it's as if 'callback' was always provided a hard copy of X at register time, on which it works internally without actually changing the real global state. I think I understand the why -- either way, the callback ends up being 'IO ()' which cannot possibly read/write any </pre> koral 2012-12-16T12:40:31 http://comments.gmane.org/gmane.comp.lang.haskell.gtk2hs/3063 <pre>Hello.

The goal of this update is to merge information that was previously spread out across several websites: http://www.haskell.org/haskellwiki/Gtk2Hs/Windows http://www.haskell.org/haskellwiki/Gtk2Hs/Linux http://projects.haskell.org/gtk2hs/archives/2005/06/24/building-from-source-on-windows/#more-15 http://projects.haskell.org/gtk2hs/download/ http://code.haskell.org/gtk2hs/INSTALL The merged instructions are available at http://www.haskell.org/haskellwiki/Gtk2Hs/Installation and at least two of the other links above are now mirrors of this website. One part of the new instructions is a collection of success reports; if you've built gtk2hs recently, I'd love it if you quickly jotted down your system configuration at http://www.haskell.org/haskellwiki/Gtk2Hs/Installation#Tested_Configurations Thanks, and let me know if there's any problems, missing information, etc. ~d --------------------------</pre> wagnerdm< at >seas.upenn.edu 2012-12-01T20:50:19 Search the mailing list at Gmane query http://search.gmane.org/?group=$group=gmane.comp.lang.haskell.gtk2hs
