in firstly, thanks for share a useful grid whit we, and i suggest to improve your nice project please ... please and please
thanks again

peterb made the start, the community can improve it more and more. I had more ideas, but I don't want
to disturb srod's Grid or other products. Beside that I don't have a personal need for it, it was just fun.

The new fun for me will be Win8 Tablets / Intel + ARM / Metro / VS2012.

Thanks to peterb for the start of improvements! Don't stop here!

Don't worry about that Danilo; no worries at all. If my controls are rendered redundant by someone else's work then I can have no complaints; that's life.

Beside's, your propertybox is cross-platform which automatically means that it offers something that my grids cannot. Mine are deeply ingrained within the Win API and no amount of shoe-horning or hopping up and down like a rabid dog is going to change that anytime soon.

If I had the time I would probably look at some crossplatform controls; but, like yourself, have no need for them at this time and I am very very busy elsewhere at this time.

Thanks for the sentiment anyhow.

I like that OS_Select macro! Too bad PB does not allow this syntax

Code: Select all

Macro OS_Select ( windows, linux, macos, def )
 
  CompilerSelect #PB_Compiler_OS
  	CompilerCase #PB_OS_Windows
  		windows
  	CompilerCase #PB_OS_Linux
  		linux
  	CompilerCase #PB_OS_MacOS
  		macos
  	CompilerDefault
  		def
  CompilerEndSelect
 
EndMacro

#PropertyGrid_DefaultItemHeight = OS_Select (20, 22, 25, 20 )    ; err! CompilerSelect not allowed amidst an assignment.
#PropertyGrid_SectionFontSize	= OS_Select(10, 10, 14, 12 )

Hello everyone,

This is my version of the PropertyGridGadget() originally done by Danilo. I use this gadget for my 3D game editor to display Mesh/Sub-Mesh information and control the Mesh rendering during the edition (hide/show some sub-mesh and use the Red Skin instead of the Blue one). The PropertyGridGadget() is the third custom control created for this project and so far it's the most complex one closely followed by the GLAreaGadget().

I have done a serious simplification to make the code more straightforward. Some feature from the original are not restored yet but it's progressing slowly. See the "Programming notes" and "What is planned" in the comment for more details.

Best regards
Guimauve

; <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
; Programming notes :
;
; 1. This PropertyGrigGadget is based on the original work 
;    done by Danilo (PureBasic English Forum).
;
; 2. The CheckBoxGadget and the OptionGadget (Added) don't
;    have a Description Gadget and Item Gadget. They are
;    created has a Description gadget.
;
; 3. It possible to select Section and Item by Index number.
;    Remember, Section Index number start at 0 and Item Index
;    number start at 0 for each Section.
;
; 4. The Item creation outside a Section is no longer 
;    possible. (See "What is planned" about this point.)
;
; <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
; What is planned (No date about when this will be added) :
;
; 1. PopupMenu to Open/Collapse/Lock/Unlock all Section. 
;
; 2. A possibility to add 3-4 gadgets has item. (For the moment
;    only 2 gadgets are possible.)
;
; 3. A better way to handle event and maybe Run User procedures
;    on specific Gadgets events.
;
; 4. A possibility to add user Data to all items.
;
; 5. Restore the possibility to add Items without Section.

Just for info an help..lines are cut

For example IsVisible is under Section04, but all do the same thing

This is a late post, but I like that OS_Select macro too, here's my alternative:

Code: Select all

; WLMO(Windows, Linux, Mac, Other) Macro

CompilerSelect (#PB_Compiler_OS)
  CompilerCase #PB_OS_Windows
    Macro WLMO(Windows, Linux, Mac, Other)
      Windows
    EndMacro
  CompilerCase #PB_OS_Linux
    Macro WLMO(Windows, Linux, Mac, Other)
      Linux
    EndMacro
  CompilerCase #PB_OS_MacOS
    Macro WLMO(Windows, Linux, Mac, Other)
      Mac
    EndMacro
  CompilerDefault
    Macro WLMO(Windows, Linux, Mac, Other)
      Other
    EndMacro
CompilerEndSelect

#PropertyGrid_DefaultItemHeight = WLMO(20, 22, 25, 20)
#PropertyGrid_SectionFontSize   = WLMO(10, 10, 14, 12)

Debug WLMO("Windows", "Linux", "Mac", "Other") + " Constants:"
Debug #PropertyGrid_DefaultItemHeight
Debug #PropertyGrid_SectionFontSize

Normally I would wrap the macro contents in parentheses, but this way it works with both numbers AND strings.
Also, I like this new name because you can't forget the parameter order.

Apparently, it's impossible to re-use the same Gadget positioning calculation. The Danilo's original code on Linux Mint + Gnome-Shell all gadget appear lower inside their section space. I will see what I can do with this issue.

Can you replace Private_RelocatePropertyGridSubItem() by this one to see if it's OK ?

Code: Select all

Procedure Private_RelocatePropertyGridSubItem(*PropertyGridSubItemA.PropertyGridSubItem, Index, Width, Height)
  
  CompilerSelect #PB_Compiler_OS
      
    CompilerCase #PB_OS_Windows 
      ResizeGadget(GetPropertyGridSubItemDescriptionGadget(*PropertyGridSubItemA), 20, Index, width >> 1 - 40, height - 1)
      
      If IsGadget(GetPropertyGridSubItemItemGadget(*PropertyGridSubItemA))
        ResizeGadget(GetPropertyGridSubItemItemGadget(*PropertyGridSubItemA), width >> 1 - 19, Index, width >> 1 - 4, height - 1)
      EndIf
      
    CompilerCase #PB_OS_Linux
      ResizeGadget(GetPropertyGridSubItemDescriptionGadget(*PropertyGridSubItemA), 20, Index - 12, width >> 1 - 40, height - 1)
      
      If IsGadget(GetPropertyGridSubItemItemGadget(*PropertyGridSubItemA))
        ResizeGadget(GetPropertyGridSubItemItemGadget(*PropertyGridSubItemA), width >> 1 - 19, Index - 12, width >> 1 - 4, height - 1)
      EndIf
      
    CompilerCase #PB_OS_MacOS
      ResizeGadget(GetPropertyGridSubItemDescriptionGadget(*PropertyGridSubItemA), 20, Index, width >> 1 - 40, height - 1)
      
      If IsGadget(GetPropertyGridSubItemItemGadget(*PropertyGridSubItemA))
        ResizeGadget(GetPropertyGridSubItemItemGadget(*PropertyGridSubItemA), width >> 1 - 19, Index, width >> 1 - 4, height - 1)
      EndIf

EndProcedure

Yes works great now !!

Thanks to fix and sharing this code GUIMAUVE

Hello everyone,

OK a little update. Have fun !

Best regards
Guimauve

Code: Select all

; Project name : PropertyGridGadget
; File Name : PropertyGridGadget.pb
; File version: 1.0.1
; Programming : OK
; Programmed by : Guimauve
; Date : 09-10-2012
; Last Update : 11-10-2012
; PureBasic code : 5.00
; Platform : Windows, Linux, MacOS X
; <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

; <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
; Programming notes :
;
; 1. This PropertyGrigGadget is based on the original work 
;    done by Danilo (PureBasic English Forum).
;
; 2. The CheckBoxGadget and the OptionGadget (Added) don't
;    have a Description Gadget and Item Gadget. They are
;    created has a Description gadget.
;
; 3. It possible to select Section and Item by Index number.
;    Remember, Section Index number start at 0 and Item Index
;    number start at 0 for each Section.
;
; 4. The Item creation outside a Section is no longer 
;    possible. (See "What is planned" about this point.)
;
; <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
; What is planned (No date about when this will be added) :
;
; 1. PopupMenu to Open/Collapse/Lock/Unlock all Section. 
;
; 2. A possibility to add 3-4 gadgets has item. (For the moment
;    only 2 gadgets are possible.)
;
; 3. A better way to handle event and maybe Run User procedures
;    on specific Gadgets events.
;
; 4. A possibility to add user Data to all items.
;
; 5. Restore the possibility to add Items without Section.
;
; <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
; Change for V1.0.1 :
;
; Removed : ClearPropertyGridGadgetSections()
; Added : DisablePropertyGridSubItem() --> "Private" Macro
; Added : ClearPropertyGridGadgetSection()
; Added : ClearPropertyGridGadget()
; Added : DisablePropertyGridGadgetSection()
; Added : AddPropertyGridTextGadget()
