[UniHTMLMemo Grow Text ToolBar Button Text Size Limit]

I have a UniHTMLMemo with ShowToolBar set to True.

 

When I click the grow text button the text size increases but it stops increasing at certain point (my guess probably due to a set maximum size).
I need to increase the text size beyond the maximum size value.

How can I do this?

[Scroll TreeView So Selected Node Visible]

At runtime I am setting the selected node however this node maybe not be in the visible area of the treeview as the treeview may contains a lot of items.

 

How can I scroll the treeview so the selected node is visible?

[ScrollBars Question]

Hi jahlxx,

 

  Thanks for that.  As you said it doesn't seem to be a problem if you are on the very latest version of FF.

[ScrollBars Question]

I have installed Build 1454 and have noticed that with scroll bars by default you have to drag the bar to scroll the contents.

 

Previously with Ext JS 4 you could click anywhere along the scroll bar to cause the contents to scroll.

 

Is there an option I need to enable to allow the above to happen?

[Sleep Delay In UniGui Application]

Can I call Sleep(500); in a UniGui application if I need to add a delay inside a for loop, or do I need use some other UniGui function instead?

 

[TUniStringGrid onDrawCell - Problem]

Yes I think that is the only way as well.

 

 

The only possible solution is to have to redo the entire stringgrid

[TUniStringGrid onDrawCell - Problem]

Hi herculanojs,

 

  Did you manage to find a solution to this issue?

[TUniStringGrid onDrawCell - Problem]

Hi Delphi Developer,

 

  Any update on this as it seems calling Invalidate does not trigger the OnDrawCell after the grid has been initially created?

 

  Build 1413.

[StringGrid Questions]

Hi Delphi Developer,

 

  If I have goRangeSelect enabled in VCL StringGrid  we can normally use the Selection property to find out what cells are selected.

 

 Is there a way of doing this in UniStringGrid as I noticed there is a goRangeSelect but no Selection property?

[StringGrid Questions]

Hi Delphi Developer, 

 

Hi,

ReadOnly = True ?

 

  I had already tried setting the Enabled to False but it grays out the grid.

 

  I want the grid to appear normally without any cell focus highlighted.

[StringGrid Questions]

Hi Delphi Developer

 

 

Hi,

 

 

And it doesn't matter which cell is selected ?

 

I don't want the cell selection to be visible on any cell in the grid.

[StringGrid Questions]

Hi Delphi Developer,

 

  Is it possible to remove the cell focus highlight so that no cell is highlighted in the stringgrid?

 

  is it possible to set the background color of the column titles row when ShowColumnTitles is True?

 

  Also is it possible to trap the click event on column title cells and then be able to call some other Delphi code?

[Fading In and Out Between Two Panels]

Hi Delphi Developer,

 

 Works Great.

 

 Thank you very much for your help.

[Fading In and Out Between Two Panels]

Hi Delphi Developer,

 

  I got around this error doing this way instead:

procedure TMainForm.UniTimer1Timer(Sender: TObject);
begin
  UniTimer1.Enabled := False;
  try
    UniSession.AddJS('document.getElementById("'+self.UniPanel2.JSControl.Id+'").style.opacity="0";');
  finally
    UniTimer1.Enabled := True;
  end;
end;

Another Question: 

 

With the fadeOut is it possible to be notified when the fadeOut has ended so I can then call some other Delphi code?  Based on what I have seen you can setup a CallBack but I am not sure how to do this and then get the CallBack to call my Delphi code?

[Fading In and Out Between Two Panels]

Hi Delphi Developer,

 

  I tried the following code to set the opacity of a Panel within a TUniTimer event with the following code:

procedure TMainForm.UniTimer1Timer(Sender: TObject);
begin
  UniTimer1.Enabled := False;
  try
    UniPanel2.JSInterface.JSConfig('style', [UniPanel2.JSControl.JSObject('opacity: 0')]);
  finally
    UniTimer1.Enabled := True;
  end;
end;

But when I do this I get the error attached.

 

Build 1413.

[Fading In and Out Between Two Panels]

Hi Delphi Developer,

 

   I found this code on the ExtJS site is it possible to get this working:

Ext.Anim.run(panelOne, 'fade', {
  duration: 100,
   after: function() {
      panelOne.hide();
    }
});
Ext.Anim.run(panelTwo, 'fade', {
  out: false,
   duration: 100,
    before: function() {
       panelTwo.show();
  }
});

[StringGrid Row Selection Issue]

Hi Delphi Developer,

 

  Is it possible to get a ExtJS 4 version with a fix for this issue?

 

  Is build 1425 the latest ExtJS 4 version?

 

  If I were to move to ExtJS 6.5 I assume I would need to download the latest beta version?

 

  How stable is ExtJS 6.5 builds?

[StringGrid Row Selection Issue]

Hi Delphi Developer,

 

  Build 1413.

[StringGrid Row Selection Issue]

I have attached a sample project.

 

Essentially it has a StringGrid which has goRowSelect turn on and has a column which is updated by a Timer every second. 

 

I am using BeginUpdate and EndUpdate inside the OnTimer event.

 

What seems to be happening is if you highlight a row and the timer updates the cells when the EndUpdate has finished the StringGrid row position goes back to the top of the grid,

rather than staying at the row you selected.  If I then try and scroll down the stringgrid the position gets reset to the top again after the timer has finished.

 

If I comment out the BeginUpdate and EndUpdate this doesn't happen and the row selector stay at the last selected row rather than move to the top of the grid.

[StringGrid and AutoSize Cell Columns]

Hi Delphi Developer,

 

  Is there any way I can do this?

[StringGrid Questions]

Hi Delphi Developer,

 

  Is there update on this as I need to be able to center an image in a cell?

 

 

Hi Delphi Developer,

 

  Another question.

 

  I need to center an image in a stringgrid cell and based on what I have seen I need to set the following in the DIV:

style="text-align:center"

 I added the following to the CustomCSS in the ServerModule:

.supergrid .x-grid-cell-inner {
   text-align: center
}

What do I need to do to apply the above CSS to the DIV?

[StringGrid Questions]

And please, can you capture an area of your app and save it directly to .GIF, for example by using LICEcap, so that we can see what's happening ?

 

In the attachment provided the row select bar is blue and the yellow first two columns are where the JS code was applied.

 

In this example you can see that the blue bar does not cover the yellow cells when the row is highlighted.

[StringGrid Questions]

Hi Delphi Developer,

 

  Would moving to ExtJS 6.5 allow me to use the CSS above?

 

  Is there a reason why it can't be done in ExtJS 4?
