Here is a fairly simple technique to allow for the resizing of objects on a window. Its best use is to provide a ‘splitbar’ type of control to dynamically shrink and enlarge the amount of space on a window a pair of datawindow objects occupy. If you really want to get fancy you will save the changed sizes as part of a user customization routine.<\/p>\n

The sample window has two datawindows positioned on the top an bottom portion of the window with a rectangle object sitting in the area between them.<\/p>\n

Example:
\n\"\"<\/a><\/p>\n

First define an instance variable on the window.<\/p>\n

Define an event on the window mapped to pbm_lbuttondown.<\/p>\n

\/\/we_lbuttondown -  using pbm_lbuttondown\n\nis_clicked_obj = ''\n\nif ypos > r_1.y and ypos < (r_1.y + r_1.height) and &\n   xpos > r_1.x and xpos < (r_1.x + r_1.width) then\n\tis_clicked_obj = 'r_1'\n\tdw_1.enabled = false\n\tdw_2.enabled = false\nend if<\/pre>\n
Now in the mousemove event on the window<\/p>\n
\/\/mousemove on window\nlong ll_y_offset\nif keydown(KeyLeftButton!) then\n\t\/\/ determine which sizing object \n\tchoose case is_clicked_obj\n\t\tcase 'r_1'\n\t\t\tsetpointer(SizeNS!)\n\t\t\tll_y_offset = ((dw_1.height + dw_1.y) - ypos)\n\t\t\tdw_1.height = dw_1.height - ll_y_offset\n\t\t\tdw_2.y = dw_2.y - ll_y_offset\n\t\t\tdw_2.height = dw_2.height + ll_y_offset\n\t\t\tr_1.y = r_1.y - ll_y_offset\n\t\tcase else\n\t\t\tdw_1.enabled = TRUE\n\t\t\tdw_2.enabled = TRUE\n\n\tend choose\nend if<\/pre>\n
Now when the user left clicks and holds on the rectangle they are able to move it up and down with a corresponding resizing of the two datawindows.<\/p>\n
