Author Topic: [SOLVED] ComboBox[Ex]: can I increase the showed lines of the Itemlist (Windows)  (Read 287 times)

 - Lazarus 2.0.6 / FPC 3.0.4 and Lazarus 1.8.4 / FPC 3.0.4
 - Windows 7 (32-bit)

I have a TComboBox (same with TComboBoxEx) with 11 items. When I "open" the ComboBox[Ex] by clicking on the DropDown-Arrow, a list with the first 8 items is displayed. To see the other 3 items, I must always scroll.

It would be "nice to have" if I could increase this number of displayed lines from 8 to 11, but I found no property for this.

BTW: on Linux always all 11 items are displayed, so no scrolling is neccessary...

My question:
Is there a property (or another easy way) to increase the number of lines which are showed without having to scroll on Windows?

Please notice, that this is only a "nice to have" for me:
 - if this could be done "in a couple of minutes", I would like to use it.
 - what I definitely not want is, e.g. to draw the Itemlist by my own (or something with similar effort), because I'm still a beginner to the LCL and would need many hours or days until it works and (at this moment) I don't want to invest this time (have enough other problems of higher prio).
Thanks in advance for your help.

Increase DropDownCount. It is the same as with standart ComboBox.
Lazarus 2.1.0 r64546 FPC 3.3.1 r40507 x86_64-linux-qt Chakra, Qt 4.8.7/5.13.2, Plasma 5.17.3
Lazarus 1.8.2 r57369 FPC 3.0.4 i386-win32-win32/win64 Wine 3.21

Try Eye-Candy Controls:

It works (both for TComboBox and TComboBoxEx)! Thank you very much, Blaazen.
