EsGRID grid gadget 2.1. Don't post here!

[srod]

Update. EsGRID version 1.1 - 12th Nov 2007.

Version 1.1 of EsGRID (please ignore the previous indexing which related to egrid and not EsGRID) is quite a large update.

Fixed a few few minor bugs and added some subtle refinements to things like grid alignment etc. The major changes come with button type cells and combo box (not editable combo boxes) type cells.

Changes to cells of type #egrid_Button :
There are now two styles of command button; 'standard' and 'flat'. This is communicated through a CellCallback function. You can also now alter the button dimensions. That is the buttons no longer have to fill the entire cell etc.

Changes to cells of type #egrid_ComboBox :
With the 'traditional' combo boxes, a row height setting for the EsGRID which is too narrow for the underlying font can cause the combo box controls to overlap neighbouring cells.
By setting the egrid creation flag #egrid_NoComboBoxOutlines (this is a 'further styles' flag) all combo box type cells will not display the main outline of the combo box control, but will instead display only the downward scroll button. Furthermore this button will be sized so that it DOES NOT overlap neighbouring cells no matter how narrow the row heights etc.

Very useful for grids with very narrow rows.

See the user guide for further details.

**EDIT : please take care with the install whilst I bully Thorsten into making an alteration to EasySETUP! Make sure you point the setup program to your PB installation folder when installing.

The EsGRID libraries have been taken down pending a new update - version 1.2.

This should be uploaded within the hour.

A new update? You spoil us. Now, to track down my reg info...

Update. EsGRID version 1.2.

Hot on the heels of the 1.1 release, comes version 1.2 !

This version adds a new type of cell, namely a custom cell.

Such cells are the responsibility of the host application to paint etc. Basically, when such cells are about to be rendered by the EsGRID library, a message (egrid_PaintCustomCell) is sent to the CellCallback function (if defined). Here, the host application is asked to paint 'off screen' to an image which is passed by the EsGRID library to the CellCallback function. The image is sized exactly to fit the cell being painted and has also been 'filled' with the background colour specified by the egrid_FormatCell message (which may involve a gradient fill of course).

The host application can of course choose not to perform any painting, in which case just the background image is displayed within the underlying cell.

Such cells are of course 'static' in that the user cannot readily edit them (although this can be gotten around with some 'creative' programming on the part of the developer! )

NOTES.

• If you are thinking that these new custom type cells are equivalent to cells of type egrid_Bitmap, then rest assure -they are not! For example, an application utilising an EsGRID using 1000 cells of type egrid_Bitmap would require storage for up to 1000 bitmaps. On the other hand, the same application using 1000 custom cells would require storage for precisely 0 bitmaps as they remain the sole responsibility of the EsGRID library which destroys them immediately after rendering individual cells!
• With regard to these custom cells. the dll versions of the EsGRID library operates slightly differently than the Purebasic static library version in that the dll versions will pass the bitmap handle of the 'off screen' image whilst the static library version will pass the Purebasic image# etc. This means that users of the static library version can use the full range of the Purebasic image library commands when painting to the off-screen image (such as StartDrawing() etc.)

As usual, the user guides are fully up to date.

How do you find the time?! Excellent work!

How do you find the time?! Excellent work!

Self-employed you see! Thanks.

Actually, all of the recent updates to EsGRID have been driven by my current work. Particularly the most obscure bug fixes imaginable! At least this way the whole library is getting a good 'road test' as I constantly ransack it and extend it etc.

[Flaming Amoeba]

Now that it is in a DLL version is there any chance somebody has converted the wrapper so it can still be used with PB 3.94?

[srod]

I doubt it somehow!

Why not upgrade to PB 4.1?

[Karbon]

Keep up the good work -- just registered a copy. I haven't actually tried it yet but plan to soon. Even the chance of it working is worth the price!

Oh, and your forum is pretty broken :

Can't create a new thread (errno 11); if you are not out of available memory, you can consult the manual for a possible OS-dependent bug

[srod]

Hi Karbon,

have just got in and haven't checked my e-mail as yet but I'll be right on your registration asap.

The forums are nothing to do with me - although I just checked the forums and it let me make a post okay!

There's another EsGRID update in the pipeline. Mainly a bugfix release, but a couple of more refinements have been included.

[Flaming Amoeba]

Karbon, it is worth every penny. I keep bragging on my golf scoring program I made with it, but esgrid is awesome and has more features than similar controls costing up to $200.00
