Omnis used the name "Complex Grids" for a reason. They are powerful, but they are complex.
Click "Run Demo" to review some complex grid notation in a demo window.The row number is not required when setting $ctarget. The target will be on the current line in the datalist represented by the complex grid.
Do $ctarget.$assign($cinst.$objs.ComplexGrid.$objs.FieldName)
Do $ctarget.$firstsel.$assign(0)
Do $ctarget.$lastsel.$assign(1000)
COMPLEX GRID $clearexceptions
$clearexceptions had always confused me. I thought it would revert the complex grid to look the way it was before I applied any exceptions.
But, it appears that the logic for $clearexceptions is to revert to the last "column" setting.
Click "Run Demo" to demonstrate.I spent a few hours trying to make use of the $fieldstyle property in complex grids only to reach the conclusion that it can't be done. Well, it can't be done for individual cells.
You can change the $fieldstyle for a complex grid column, but you can't change it for a single cell in a column.
Tech Support confirm this and suggested that this "feature" won't be changed.
To work around this problem, you need to "relax" the #STYLE restrictions on the $fieldstyle properties that you want to be able to change for individual cells in your complex grid. You can then modify the individual property, instead of trying to change the $fieldstyle.
Click "Run Demo" to demonstrate.If you have a reference to an object in a complex grid, how do you know which column of the
complex grid it is located in?
If you have a reference to an object in a complex grid, how do you know which section of the
complex grid it is located in?
The $gridsection property will tell you the answer. $gridsection returns the following
constants: kGridColumnHeader, kGridHeader, kGridNone, kGridOther, or kGridRow
To add columns to a complex grid you need to add a divider to the $dividers group.
Do $cinst.$objs.GRID.$dividers.$add(POSITION) Returns rDividerIf the complex grid $enterable property is set to kTrue, the user can no longer select lines the same way as in a headed list.
This tip shows how to add a simple $selected checkbox to the complex grid. Click "Run Demo" to demonstrate.Need a clean looking complex grid? Why not make it look like a spreadsheet?
This demo also provides code for having the up and down arrow keys moving vertical from cell to cell in the complex grid.
