Gtkdialog Development
thunor,
When I asked the question as to where, scOttman's post read completely different.
He edited it after my reply.
ScOttman,
I have looked at your program and I see what you meant about the play button being grayed out.
If you think that is because of a nonexistent file just search for it differently.

sorry about that, thought I would dig out the actual code.8-bit wrote:thunor,

I have noticed too whilst travelling through the code that some consistency is required with regards accepting values. I have made a feature request within the issue tracker so that it gets dealt with.sc0ttman wrote:...but there seems to be a slight lack of consistency
- Some options are allowed here, but not there..
- options seem to take xxx="yes/no", others xxx="true/false" or maybe xxx="0/1"
For example, I often wonder why "width-request" and "height-request" are allowed in some widgets, but are NOT allowed in others..
GTK+ widgets have an ancestry, so that they inherit from their ancestors. "width-request" and "height-request" are properties of GtkWidget which everything is a descendant of, therefore you should be able to apply these to any Gtkdialog widget.
GTK initialises some widgets the first time that they are shown and this can make applications spring back to the middle of the screen if Gtkdialog's "--center" option is used -- I've noticed this whilst working on the menu system -- and a remedy for this is to use a "width-request" somewhere, likely on the window if there are multiple causes.sc0ttman wrote:Open VLC-GTK, and drag the window away from the centre of the screen.
Then click on the 'Streams' tab.. The sizing make the window move..
The same thing happens with the 'General Settings' tab at the bottom.

Just FYI, it looks like Flash has got around to making the package collections/repositories section publicly visible, so everyone should be able to see the "Index of programs using gtkdialog" now
Thanks Flash - I was starting to worry this was becoming like the Ubuntu forum, where you seem to need to be logged in to read half the pages, or download attachments, or whatever...

Doesn't it make more sense to start with the refactoring? that way you have less to refactor and it makes it easier to do the other work...thunor wrote:I want to add new widgets, overhaul existing widgets, implement missing action functions, finish the wiki, write some more examples, even restructure the code so that one widget is in one file with everything in a consistent order so that I don't have to keep searching the entire session to find things. These things to me will improve Gtkdialog.

Overhauled the menu and menuitem widgets - final
The widget reference is available here.
Updated 2011-08-07 22:11 to include a theme icon menuitem with a requested size of 32 (value goes into either the width or height directives and you'll get that size if it's available).
<menu> and <menuitem> widgets example:

Updated 2011-08-07 22:11 to include a theme icon menuitem with a requested size of 32 (value goes into either the width or height directives and you'll get that size if it's available).
- Added support for submenus by nesting the existing menu widget.
- The menu widget -- being essentially a menuitem with a submenu -- now supports the same tag attributes and directives as the menuitem widget.
- Added support for images from files via the "image-name" custom tag attribute (scaling works too).
- The image from file menuitem widget supports the disable, enable and refresh action functions.
- Created a new name for the existing separator widget: menuitemseparator.
- Added checkbox and radiobutton menuitem support via the "checkbox" and "radiobutton" custom tag attributes.
- The checkbox and radiobutton menuitem widgets support the disable, enable, refresh and save action functions.
- The theme icon menuitem widget now supports using the height or width directives to override the default theme icon size of 16.
<menu> and <menuitem> widgets example:
Code: Select all
#!/bin/sh
# NOTE: This example requires at least gtkdialog-0.7.21 (please visit
# http://code.google.com/p/gtkdialog/). Additionally if you are using
# Puppy Linux then you may find that an historical version of gtkdialog
# already exists in /usr/sbin, and if that is the case then you should
# modify the shell variable below to point to the new gtkdialog binary.

Comparing dotted version numbers is now easy. Woof as from April 2011 has 'vercmp' which will be in all Puppy builds, both in the initramfs and in /bin. See my blog post:thunor wrote: Retrieving and Testing Against Gtkdialog's Version
The fact that Gtkdialog went from 0.59.8 to 0.6.0 in 2006 slightly complicates the process of checking the version number, but the following code does the trick (on Puppy Linux you will get "5908" for gtkdialog2, "7020" for gtkdialog3 and "7021" and upwards for gtkdialog):Code: Select all
GTKDIALOG=gtkdialog function funcGTKDVGet() { GTKDV=( $($GTKDIALOG -v) ) GTKDV=${GTKDV[2]} echo "Gtkdialog version: $GTKDV" GTKDV=( ${GTKDV//./ } ) if [ ${GTKDV[1]} -lt 10 ]; then GTKDV[1]=${GTKDV[1]}0; fi if [ ${GTKDV[2]} -lt 10 ]; then GTKDV[2]=0${GTKDV[2]}; fi }; funcGTKDVGet if [ ${GTKDV[1]}${GTKDV[2]} -lt "7021" ]; then echo "This application requires at least gtkdialog-0.7.21" exit fi
http://bkhome.org/blog/?viewDetailed=02226
Example:
Code: Select all
VER1=0.7.21
if vercmp $VER1 gt 0.7.20 ; then
echo 'greater than 0.7.20'
fi

I'll update my main post with this information
BTW I've gone through the examples within the repository and fixed-up the quirky ones and commented within the broken ones. I know you said that you were putting together a collection of new examples so why don't I give you developer access and you can do it all in the repository. Then if you want to change all the "GTKDIALOG=gtkdialog" to "GTKDIALOG=gtkdialog3" then you can do it with "sed" on a local copy before you create your pet. Let me know if you're interested.

Improved the theme icon support
The menuitem widget reference is available here.
The button widget reference is available here.
The pixmap widget reference is available here.
I've updated the menuitem, button and pixmap widgets to support using the height or width directives to override the default theme icon sizes of 16, 20 and 32 respectively.
If you want to know a bit more about what's going on here, theme icons are loaded using the GTK+ gtk_icon_theme_load_icon function and one of its parameters is "size", so if you declare something within the height or width directives then that's what I'm setting "size" to, else I use a default. Note that "the resulting icon may not be exactly this size".

Whilst working on the new spinbutton widget I unearthed a bug in the tag_attributes.c:try_set_property function, the function that is responsible for passing tag attributes that are GTK+ widget properties on to GTK+ to set. The part that was responsible for converting char strings to unsigned integer values wasn't converting to anything, so that's why the "border_width" GTK+ property always appeared to be around 50 -- "0" being ASCII 48, "1" being ASCII "49", "2" being ASCII 50 etc. etc. Therefore the GTK+ "border_width" property now works as expected and this affects quite a few Gtkdialog widgets descended from the GtkContainer class. A short while ago I created the h/vbox and window "margin" custom tag attribute to compensate for this problem but it would appear to be redundant now (I'll leave it in though as it might be being used, but I'll remove it from the documentation).

Pmusic 2 is taking advantage of your wonderful work. Of course I meet some challenges, and I thought I would share some of them.
1.) H O T K E Y S
If I use <menuitem visible="false" accel-key="0xff52" accel-mods="4"> the hotkey won't work - because visible is set to false. Is this defined by purpose? I see it as a nice way to include hotkeys for other functions than I would like to include to the menus. In this example I want CTRL+up to increase volume level, but find it unlogical to include a menultem as the <hscale> works very well as the gui-alternative for setting volume level.
2.) P R O G R E S S B A R
Pmusic is getting more complex, and some parts of gtkdialog is not friendly to projects like Pmusic. - i.e. I let the main <progressbar> handle the refreshing of
- position of progress <hscale>
- album art for playing song
- play or pause icon in button
- playlist content - to show new items added from external source (like filemanager and external Music-source-window)
The problem is that <hscale> preferable should be updated each second. But this will deselect whatever the user has selected in the playlist <tree>, and that is rather anoying. The best solution for the <tree> would be to refresh only when the user actually adds something, but this won't move the progress <hscale> very often. A solution would of course be to use a unique <progressbar> for the refreshing of the playlist <tree>, but this would steal cpu, and Pmusic is aready using enough cpu-power.
The idea to solve this is hopefully simple:
<input file> is not in use by <progressbar> and could contain a value used in <action>if value refresh:PLAYLIST</action>. In other words; if <input file> contains 'refreshplaylist' (or whatever value) the playlist should be refreshed. Like this one progressbar could be used as a refresh-hub, and gtkdialog would be useful for BIG projects.
The very best would be if the <input file> could hold several values and the <action> activates if one of the values matches. This would make it possible to refresh several widgets, - or just one of them...
3.) C H E C K B O X
Pmusic 2 is close to beta-stage, but still there is one thing that is holding me back from freezing the new graphical theme-standard. You have worked alot with improving the pixmaps in gtkdialog. Still, I am not able to use the <draw-indicator="false"> for <checkbox> with only showing a pixmap (no label). Most audio-players uses only icons on the checkboxes for 'loop' and 'shuffle'. This is not a big thing for me, but I have to decide before I announce the grapical theme-standard for Pmusic 2 as final.
Thanks a lot for you work

A quick question about the GtkDialog <notebook> widget.
I see multiple entries in xerrs.log when using the mouse wheel to switch between tabs of a gtkdialog GUI constructed with the <notebook> widget.
For example, using the mouse wheel to switch tabs in 'Puppy Event Manager' will quickly fill xerrs.log with the following:

Hi Sigmund
1.) H O T K E Y S
GTK+ disables the accelerator with the menuitem.
2.) P R O G R E S S B A R
Sounds to me like you need a proper timer widget like the one described here -> http://code.google.com/p/gtkdialog/issues/detail?id=15. I'm working on the spinbutton widget at the moment but I can add the timer widget pretty easily if you want me to.
3.) C H E C K B O X
I can add one of these (togglebutton widget) equivalent to our existing button i.e. with label/stock/icon/pixmap but it'll toggle. If you need this widget as soon as possible then it could be done by the weekend.
@radky: I get that too. Just note if for the moment.

Sounds to me like you need a proper timer widget like the one described here -> http://code.google.com/p/gtkdialog/issues/detail?id=15. I'm working on the spinbutton widget at the moment but I can add the timer widget pretty easily if you want me to.
In the Puppy world we should never rush . Please consider it as a suggestion, and do what you feel like. I will sure use a toggle-button if it exist. - If not, I will use the already working checkbox. I can release the Pmusic beta and make a note about the not finished theme-standard.thunor wrote:3.)

I can add one of these (togglebutton widget) equivalent to our existing button i.e. with label/stock/icon/pixmap but it'll toggle. If you need this widget as soon as possible then it could be done by the weekend.

Added spinbutton widget
The widget reference is available here.
Updated 2011-08-10 16:34 to illustrate that it's effectively an entry widget with an attached h/vscale widget.
You can see in the terminal that spb1 executes action functions at start-up and this is due to GTK+ emitting both "changed" and "value-changed" signals on application of the "digits" property. Just to note that it's GTK+ doing this on widget realization and not Gtkdialog so I'm not in a position to do anything about it.

Updated 2011-08-10 16:34 to illustrate that it's effectively an entry widget with an attached h/vscale widget.
- The default signal is "value-changed", emitted when the range value changes.
- The "changed" signal is emitted when typing into the entry.
- The "activate" signal is emitted when the user activates the entry with the Enter key.
- "range-min", "range-max", "range-step" and "range-value" are custom tag attributes that accept double precision floating point numbers (the GTK+ "digits" property specifies the number of decimal places that are displayed within the value).
- Use either the "range-value" custom tag attribute, the <default> directive, the <input> directive or the <input file> directive to set the spinbutton's value.
- Use the custom tag attribute block-function-signals/block_function_signals="true/yes/1" if you want to isolate signals originating from user widget manipulation from the refresh function.

I am picturing spinbutton used in combination with toggle.
Instead of 4 buttons of "Enable", "Disable", "Refresh", and "Save",
there would be 3 buttons.
The "Disable" button with icon would be shown and when clicked on besides disabling the entry box, would change to a "Enable button with icon".
Each time it was clicked that button would change to it's opposite button and also change to enable or disable the entry box.
It would allow making a smaller application window that still functioned as it should.
