Hi All

This is a UI component that we need and thought we can share with you, hope it’ll be useful.
Comments and feedback are welcome.

Main Functionalities:

  • Variable Number of Row and Column Headers
  • Hide/Unhide Row or Column: Toggle the visibility of rows or columns.
  • Freeze/Unfreeze Focused Cell: Use the contextual menu to freeze or unfreeze the focus cell.
  • Move Focus Cell: Navigate between cells.
  • Resize Row or Column
  • Block Selection: Select multiple cells using Shift + Arrow keys, or using left click
  • Select Entire Row or Column: Select an entire row or column with Ctrl + Shift + Arrow keys.
  • Customization Options: Customize background and foreground colors, fonts, alignments, and more.
  • Cell Types: Support for two cell types—Text and Checkbox.

How to Use MyGrid in Your Xojo Project:

  1. Copy the MyGrid.xojo_window file to your project directory.
  2. Import the copied file into your Xojo project.
  3. Drag the MyGrid component onto your window to start using it.

Additional Information:

  • MyGrid has been ported from another language to Xojo with the original author’s permission.
  • Licensed under the MIT License.

I’ve also included a file with MyGrid and a demo project to help you get started.

Hi,
I compiled on Mac Sonoma 14.5. Crash when clicking on cell or on "Show sample grid’. Can send you crash report if you want.

You may want to read this:

Xojo Roadmap. Of course, there is no date of release.

even if xojo releases one day something similar, I really prefer to have an open source alternative I can modify if I need !
in fact I would really like xojo to release the framework open source, all the bugs and non working parts could have been corrected by the community long ago …

I once ago used a nice dev tool called Prograph, that worked this way. all the framework was open source, and you could also change many parts of the IDE. has been rewritten under the name “Marteen” and is no more updated but should still work under non silicon proc.

Yup. Makes a hard crash for the sample grid on Sequoia, too:

the crash arrives at the first

me.ColScroll.MinimumValue = me.FrstTopCol

in the AdjustScrolls method of the grid…

That’s why i made XojoEZUnit! XojoUnit was even open source but i wanted different ways of using it and an easier setup, Open source is great!
